This is a great chart on the morphology of of mushrooms, there is a mycological jargon that can be very confusing, this helps with the basics of mushroom structure.
There have been a number of letters to the editor lately concerning bikes on the B-Line, and truth to tell, it is a difficult set of laws that must be perused to fully understand the proper procedures.
This where most of the confusion exists:
TRUE or FALSE
Bikes must stop/yield at the B-Line crossings.
TRUE! There are Stop signs as each crossing, and text that declares “Cross Traffic Does Not Stop”. These signs are for bikers only, but some people do not see them, or ignore them. Many bikers seem to think they are pedestrians, but they are not. In fact they are vehicles according to state law (IC 9-21-11-2) On the B-Line confusion seems to be that many people believe that motor vehicles should stop for both pedestrians and bikes when on the trail, but this is just not case in Indiana. If a pedestrian is on a curb at an intersection, then “…a person who drives a vehicle shall yield the right of way, slowing down or stopping if necessary to yield, to a pedestrian crossing the roadway within a crosswalk when the pedestrian is upon the half of the roadway upon which the vehicle is traveling or when the pedestrian is approaching closely from the opposite half of the roadway. (IC 9-2-18-36)”
This sentence contains a lot of info. It may seem a bit strange, but motor vehicle operators are required to slow down or stop only once a person has stepped into a crosswalk on the side of the street on which the car is traveling. Once you closely approach the other half of the street (this is not an exact distance in this code), then cars are required to yield or stop. This not true for bikers, unless they dismount and walk their bikes across the street, as then they are pedestrians.
On the B-Line, I most often see cars stopping for pedestrians and bikers who are waiting to cross. This is great, Hoosier Hospitality at its best! However, it is not required by law unless the pedestrian has entered the crosswalk, so there is no reason to become annoyed or angry that people are not stopping for you. Better to take a deep breath and enjoy the beauty of life in the open air, and pity those stuck in their iron cages.
Bikers are not pedestrians, they are considered non-motorized vehicles, and should stop at the B-line crossings, and wait for traffic to clear. Even if you poke your wheel into the street, hoping the cars will stop, you could be cited for obstructing traffic, and if you were hit, you would be at fault.
Even pedestrians must be careful about stepping out into the street: “A pedestrian may not suddenly leave a curb or other place of safety and walk or run into the path of a vehicle that is so close as to constitute an immediate hazard. (IC 9-21-17-5)
So pedestrians should not jump in front of moving motor vehicles! This seems rather self evident, but this codifies the concept. If you do this, the police can (and have in the past), follow the ambulance to the hospital, and issue you a citation.
All this being true, there is still this requirement for vehicle drivers:
Sec. 37. Notwithstanding other provisions of this article or a local ordinance, a person who drives a vehicle shall do the following:
- Exercise due care to avoid colliding with a pedestrian or a person propelling a human powered vehicle, giving an audible signal when necessary.
- Exercise proper caution upon observing a child or an obviously confused, incapacitated, or intoxicated person.
Traffic control signals not in operation
So according to state law, cars do not have to stop for pedestrians unless they are in the crosswalk. This is not the case in all states, but it is here in Indiana, as well as Vermont and Florida. So it is polite to stop your car for pedestrians at the B-Line crossings, but it is not mandatory, it is not law.
Roadways; rights and duties (for bicyclists)
Sec. 2. A person riding a bicycle or operating a Class B motor driven cycle upon a roadway has all the rights and duties under this article that are applicable to a person who drives a vehicle…
On the B-Line, there are stop signs not on the roadway, but on the B-Line itself, and these are meant not for the pedestrians, but rather for the bikers. The signs on the road read “Cars must yield to pedestrians in the crosswalk”, the functional important parts being “pedestrians” “yield”, and “in the crosswalk”, (not on the sidewalk).
To say the least, this is not clear to most users, but it is the case. If you were to ride out into the intersection without first stopping (blow through the crossing) and get hit, you would be cited for the infraction, not the motorist, even if they had time to stop. Unfortunately that is the law, and the tradition; police often see themselves as the guardians of vehicular traffic, and like many motorists, can see pedestrians and bikers as impediments to motorized traffic, rather than seeing them as traffic itself. Of course we are all traffic, people trying to get from one place to another, but the culture is currently weighted to favor motorists. We are trying to change this balance, and in fact Bloomington has one of the highest percentage of non-motorized commuters in the US, nearly 5%.
Be careful out there!
The first spring wildflowers poked up their heads in Dunn Woods during the week of February 22. There are several bunches of snow drops, aka Galanthus, often the first wild flowers to appear this year. I will be finding salt and pepper (harbinger of spring, Erigenia bulbosa) in the deeper woods soon! Below is a link to Kay Yatskievych‘s Flower Finder for Indiana Spring Wildflowers, the single best resource I have found for indenitying Indiana’s emphemerals. Happy hunting!
This year was the best year in a decade for ice biking (and skating) on Lake Griffy.
The ice was 4 inches thick, and completely clear and slick. There was a deep freeze, and no snow, sleet, or rain had marred the surface, so it was perfectly smooth. So how does a bike work on smooth clear ice? Perfectly well, thank-you! There are several tricks to biking, and staying on your bike, on ice. First, do not push hard on the pedals! That will cause slipping for sure. Start slow, and keep adding just a small amount of power to your spin till you are going at a reasonable speed, which on ice is usually less than 10 mph. Second, don’t turn quickly, your front tire will slip, and down you will go. Third, be very careful when braking, in fact the best policy is to leave them alone; don’t put yourself in a situation where they are needed, and you will be fine.
About tires: Nothing special is needed, though I assume having studs would give you the ability to move faster as you would have better traction. But this is has not been necessary for me. A couple years ago I had slicks on front and back, and they worked great! More contact with the ice gave me better traction. This is not true for snow, where having tread really helps gain traction. Snow riding is a bit harder than ice riding, but just as much fun, there is no doubt.
After a week or so, a light snow covered the surface of the ice. I could not tell if it was more or less slippery than clear ice, I think it was a combination of factors each way so that it was a draw, though it was just a little harder to pedal.
The snow it did not slow down the intrepid skaters Michael and Jenny, who explored the deep end of the lake with me.
I know that separated bike paths are a great idea, it certainly makes biking feel safer, in most cases. But as I was riding to Griffy Lake the other day, I noticed that car drivers can and do make some mistakes that threaten even well separated bike paths. This picture was taken on Old 37, just a hundred yards from the intersection of Cascades and 4 lane Walnut not far from Griffy Dam. The sign says 30 MPH, but the motorist who ran into it, and onto the bike path must have been going much faster.
It was a great morning when I got to sing tunes at the Bloomington Farmers’ Market with both Dexter and Charlie Bird of Bloomington helping out!
After five years of bike riding, hiking, canoeing, and now sledding, Charlie Bird of Bloomington has learned about flying!
As he grew up in a cage (20 years), he never learned to use his wings to fly. Sometimes when we ride downhill on the bike we has flaps his wings a bit, but never fully spreads them out fully. On this trip down the hill at Butler Park, he got his wings fully extended and decided to flap away. I lost track him for a few seconds (I was tubing too), but you can see him sitting next to the slide at the end, he landed softly in the snow.
Mitch and Charlie Bird Tubing, and here he flaps midway down
Here Charlie Bird Flies!
Here is a video we recently did at IU Communications, my voice-over career is back on track! ;~}
Charlie the Bird of Bloomington does not mind the cold weather (he wears a down coat under his colorful feathers), and in fact loves to go sledding in the snow.
