I got a ticket from the Ames Police back in 2000 for riding down the road onto the sidewalk by the Welch Ave ATM (across from the FD) and 20 feet later to the Bike area to lock it up so I could get a haircut at a business on Welch.
$86..... because I rode my Bike on the sidewalk for 20 feet. I remember him calling my name and description of my Bike on his Walkie. Writing me a ticket and that was it.
That is what always gets me. Drivers do not realize it is illegal to ride on the sidewalk. We have to be in the road. It is not safe for a bike to be on the sidewalk.
