Had a thought on day 2 (yesterday), but forgot to post it yesterday. Surprise! The thought: "Never accelerate towards a red light." Follow-up thoughts mostly involved trying to figure out how to succinctly say "a light that will be red when you arrive," but came up with nothing elegant. So I stuck with the original thought.
I'm going to need to find some kind of bicycling lj icon, aren't I? Maybe something Yehuda Moon-related, except that seems to have gone on hiatus. Oops.
