Matthew--
You're in the middle of God's country! Review with your CFI what makes a "good" forced landing site, and practice looking for them. I-26 is about the only decent road around, and often low traffic once you get away from Johnson City, but it gets pretty steep. Corn and bean fields can be attractive. Be careful, though--someone ran out of fuel near Asheville a couple of Decembers ago and hit trees on his approach into a pasture, which turned it almost vertical. That is stuck in my memory because it was my model of plane, and I fly into KAVL when visiting Mom & Dad.
Find something that looks good from the air, then drive past it and look for power lines, poles, signs, gullies, etc., and it will improve your ability to find good alternatives.
