Ran into these two bicyclists riding west a few days ago. There were really cool, and impressed by my chocolate-milk-drinking-while-riding.

Some other cross-country-traveling people I've met on this trip include loads of people driving, and quite a few cyclists.
A few include:
Chris Young is riding west for the Heart and Stroke foundation.
The other day a guy called Geoff Stopped to see what I was up to. Though not on the trek at the moment, he's paddling with his wife and dog in a canoe from west to east! It's a project they've been on for several years, very impressive.
