I'm going to go to the tea shop on Alberta, get a table outside, and start counting bicyclists that go by. Maybe I'll count the next 100 bicyclists, maybe I'll stop when I get bored.
What percentage of bicyclists will be wearing helmets?
I'll give some kind of prize to whoever gets closest.
UPDATE: I observede about 84 cyclists in about as many minutes. 38 were wearing helmets, which makes 45%. So ms_nico_blue
are the winners. Now I have to figure out what they win...
