Or rather just attaching my GPS unit onto my bicycle. Many people just go and get one of those little digital things that tell them how far, and how fast. I was going to get one of those too, but then I remembered, that hey, I've got this GPS thing that I only really use when I vacation. And you know, that will tell you how far and how fast and which direction and elevation. And then you can go and build maps of where you've been afterwards! (Technophile? why yes, thank you.)
This is just too entertaining, I might pop.
This is also where I start to think it is a good reason I don't have a GPS Unit that can show color maps. I'd never watch where I was going, just looking at the screen instead. (And that's just an accident waiting to happen.)
