Walking along the sidewalks on major roads, there's a 2 to 3 foot high snowbank between the sidewalk and the street, about 5' wide at the base, and 18" wide at the top. It makes crossing the street as a pedestrian challenging.
Unfortunately it occupies the space that most signs, parking meters and bike racks occupy as well- can you see the top of the bike rack in the photo below?
I saw this bike, parked in defiance of the snow- on TOP of the bank. Makes sense I guess.
