“Ever bike? Now that’s something that makes life worth living! I take exercise every afternoon that way. O — to just grip your handlebars and lay down to it (lie doesn’t hit it at all) and go ripping and tearing through streets and road, over railroad tracks and bridges, threading crowds, avoiding collisions, at twenty miles or more an hour, and wondering all the time when you’re going to smash up.”

-Jack London, in The Letters of Jack London
