Welcome to the club!
I'm actually headed to Chattanooga tomorrow to hit a trail called Haley Rd. in the Prentice Cooper WMA with a guy from the NOAS club (noas4x4.com) and then headed to Coal Creek near Oak Ridge that night.
You should come hit Haley Rd. with us if you can. We are meeting at the Subway on Signal Mountain Rd. off of Hwy. 27. And you're welcome to come to Coal Creek as well. It's a huge OHV park (72,000 acres, 160 miles of trails) and plenty of trails for a 4x2 to handle and can get as extreme as you're willing to push it.
Here's the link to the forum posting with the details.
