* I know how many this time, because I used Toby's bike, which has a working electronic thingy that tells you how many miles you've gone, etc. Unlike mine, where the electronic thingy broke six months after I got it, and I never got around to getting it fixed. :D So I may revise my miles-per-hour guess up a bit, as I've gone a mile farther than I usually would have in 30 minutes.
