I don't think it's about a "westerly bias", I think it's more practical than that: There just isn't that much public land East of the Mississippi that's explorable by off-road vehicle. You are either traveling on paved or well graded dirt roads that any vehicle can traverse, or you're on foot - there's very little "in between" area that is accessible by a 4x4 but not by an ordinary car.
