I live in Chicago. We have a lot since two small, easily bridgeable rivers go through the entire city. They don't last long, maybe 50 feet. I just slow down to maybe 10 MPH when it's wet out. A couple are terrible and I go maybe 5 or less when wet when I cross those. I never have fallen yet. Don't try to change direction much on them. Knobby tires are terrible on them, but as far as slicks go, the fatter ones are better.
