The U.S. Postal Service will issue a new stamp celebrating bicycling next week, and it's chosen Minneapolis in which to issue the "first day cover," because it is America's #1 biking city.
I have noted on this blog numerous times that I might bike more if I had the Spandex and biking wardrobe that my bicycling friends assure me that you don't actually need in order to fit in with the biking community.
I say the U.S. Postal Service wouldn't lie about such things.
If you want to just wear normal clothes while biking, you better have training wheels on that thing!
