Great! Commuted to kindergarten w/ Thing1. I've been working on him to get him more confident riding in the street (it's flatter, smoother, much easier for somebody riding a little bike that is about a third of his body weight, and he can roll through intersections where he has the right of way, which I won't let him do when crossing the street from sidewalk to sidewalk), but he prefers the sidewalk lately, so I followed him in a 24" gear, roughly 2.5 mph. We parked our bikes together in the rack, went in w/ his stuff, and then off I went to come into work. When I got up to speed (or past say 5 mph), I could hear this annoying squeaky/raspy sound, something binding/scraping both wheels, so that bugged me the rest of the way into work. I might poke around at them before I take a lunchtime ride (since I have a roadtrip for work and won't be biking again until I go home Wednesday).
