Things I've seen:

Two kids on one bmx bike, the passenger in front of and blocking the view of the pedalr, crossing Hiawatha ave on a diagonal, not even looking for cars in either direction. They made it somehow.

Some of the Major Taylor bike club out for a ride. You should read up on Major Taylor. Interesting interesting guy.

More bike commuters. Many more.

Some one fatter than me riding a bike. That is hard to believe, I know, but it happened.

At least 2 different Big Dummies, one extracycle, and several trailers.

Shortening days.
