I took my completely stock TJ on all the trails except Daniel when it was stock. You can even to Rocky mount, just take all the bypasses. You stock or near stock jeeps are really more capable than you can imagine. The 3 roughest trails (and by roughest I don't mean "hard" by any means) is Daniel (of course), Rocky Mount, and Dickey bell. And with that, Dickey bell has only 1 spot that would be considered difficult. Oh, its NOT difficult, I took my stock Jeep up it. Go with friends, you'll be kicking yourself all day for waiting so long to go.
Common sense is surprisingly, not that common.
