I laughed.
We have a few people nearby here that only travel by bike. I don't think it's for health reasons, I think it's monetary or based on losing their licenses or whatever (they come out of the trailer parks) (no hate, just saying)...they're always in pretty ragged clothing, etc. Most of them walk their bikes up the slightest incline, but a few of those dudes can really hammer. The one guy has an older bike with drop bars, and I'll see him trucking along with his groceries on the handle bars and everything doing 20+ uphills all day.
