SaabZombie, mentioned some of the same, concerning Patton Cave, and I would think we should probably count on that in general, for all these old SAS trails, except for perhaps, Nebo Ridge, Axsom, and Sycamore branch trails.
It's probably been plenty long enough, to assume few of the listed Landmarks, will be of much help.
Quite a few deer hunters do use Crooked Creek Lake, to park vehicles, and I know they at least use to be able to 4-wheel into Will Hayes or Panther creek valley, from some other access.
At one time, it use to be a prime opening day location. We came down off the ridge into the valley and you could count the little orange "dots" all over the little pine plantation, which like Mule mentioned, is now nearing mature growth and practically unrecognizable, from the 8=10' trees that use to make it up.
Can we do it? Who cares. Any reason to get out in the woods, where other people possibly haven't been for awhile, is kind of a rare thing, in Indiana, now days. HF'rs have been tramping around Nebo ridge trying, and doing a fine job, of getting turned around, for quite a while now. Why should Nebo get all the action?
