I'm pretty much a lifelong non-owner of a bicycle, and I've certainly never done city biking in traffic, but I just got one yesterday. So be prepared for many future posts about the low quality of America's bike infrastructure and how we should be more like Amsterdam or Copenhagen. For example, the city fathers of Washington, DC should consider that though it's nice that they've established some bike lanes, the key thing would be for the lanes to connect with one another and go into the downtown area so they'd be helpful for people trying to get from where they live to where the bulk of the stuff is.
It's like how the roads for cars don't just stop arbitrarily. Think about it. Also, to the bike thieves of the world -- don't steal my bike!
