Ok, this is a GREAT idea for anyone who is walking, running, or otherwise trying to do some kind of distance work. My only complaint - it would be nice if there was some kind of input to switch locals. Say a zipcode box.
I work as a computer programmer by day, but at night I study metaphysics, play tai chi, and otherwise do non-technical stuff. I have a love of walking and watching movies. I like to read and never seem to spend enough time doing it. I also like to do genealogy, but again I do not spend a lot of time doing that as well (or at least as much as I would like).
