RE: Oak Thickets
Sounds like an area I've hunted.
Another thought about all those fingers and ridges...
If you're on the move during the day instead of sitting on stand, and are walking the ridgetop, keep an eye out below you. I can't tell you how many deer I've jumped that were just out of sight bedded down about 1/4 to 1/3 the way down the hillside at mid-day.
Good luck.
