I wouldn't do it again.
But you probably wouldn't walk the same path as the crow flies. Where I hunt elk is 7 - 10 miles as the crow flies from the nearest open road, but you'd never walk the shortest distance as you be doing some serious climbing and descending and then climbing again, I follow the drainages in and out, which is a few miles longer but much easier.I beleive the farthest you can get from a road in the lower 48. Is in the Thorofare in Wyoming about 18 miles.
