I'd like to add something to this list of things the bike lane is NOT for: storing snow.
This is especially problematic when snow is being stored in protected bike lanes - you can't get around it!
If you're going to store snow somewhere, put it in the street so cars can run over it...
I rode my bike for the first time in weeks today and I had to weave in and out of the bike lane on Columbus because there were whole blocks where there were giant piles of snow in the bike lane...NO. BUENO.
