My own approach is a variation of the same game, just one that is played on a smaller chessboard and with considerably older legs. I'll map out the public trailheads on one front of a range, then link the access points with straight lines. The midpoints along these lines, between any two accesses, may not be too far back into the range, but the country will be tough to reach. What I am looking for are forested ridges that finger sharply down onto private ranches in the valleys. Hunting pressure from the ranches often creates a daily migration pattern, with the elk feeding on the ranchlands at night, then climbing back into thick timber on the public lands to bed during the day.
