I plan on training this summer out in Flagstaff. I hear there are BLM lands you can camp on for free. I figure if I attach 4 small off-road wheels to the base of a cheap plastic she'd from home Depot I can push or pull it 25 miles to a new spot every 2 weeks or however the rules go. I'd start it on a hillside of a mountainslope and push it down for two months. Where is the best long or undulating hillside to do this? Ideally there is fresh water and a major road for catching rides.
