RE: South East Oklahoma
Garminator, by 'rough' I mean rocky, steep and thick brushin some places. The weather can also change quickly, as stated by Moose Maximus. I have seen thick clouds of fog roll in out of nowhere. Also, try to familiarize yourself with the area before you head out. It is very easy to get lost. Most of the mountains run east and west and look the same. Find some landmarks to navigate with and you'll be fine.
They do allow hunting in the Ouachita National Forest but there are specific regulations that you need to read up on before you head down there.
