I hunt a much smaller WMA that is only open a couple of times during the seasons for a few days at a time. It too has roads throughout, but the back half are cut off from vehicle traffic for the turkey hunts. Still the access is very easy on that place, and people hunt all corners of it, the place gets packed on Saturday mornings. It doesn't bother me though, the hunting can still be good. Sometimes it's not all about going in farther than the rest, it's about working around them
