I've hunted there the past 4 years, with 1 doe harvest and a missed opportunity on a good buck. I live in Chattanooga so it's a short drive for me. Here are some of the things I've learned from hunting there:
Get out there ahead of time if you can and put some boots on the ground. I must've have hiked ten miles and driven 30 last year scouting. Bring a map and plenty of water, cell service isn't great up there.
Buy a thermacell! I'm a believer and will not hunt this hot weather again without it.
Be careful driving in. It seriously is like the Daytona 500 once that gate opens and people drive like idiots.
Alot of guys will hunt less than 200 yards from their trucks. Don't get your feelings hurt if you park off the main Rd, walk 3/4 mile down at dirt only to find someone parked right where you thought you were "slipping in" at.
Have a large cooler with ice ready! Last year I harvested a down at 9 am. By the time I got her out of the woods, checked out with the wardens, and hanging at the house it was 11 am. It was 77 degrees and rising, you have to clean a deer fast!
Get there early and have back up plans. I actually shot my deer last year in one of my backup spots.
Be nice, everyone there is excited about the start of deer season and might even give you a pointer.
If you leave for lunch, go to Shuford's BBQ at the end of the Suck Creek Rd. The food is so good that I'll forgive them for all of the Crimson Tide memorabilia on the walls...
Good luck- Dirt
