Digging this thread from it's grave. I'm in Porterville, about 30 minutes south of Visalia. I've made a little JeepForum Group. (CentralCal 4x4 - In my sig) Local Jeep here has a Lock and Low sticker on the back of his window. I checked out their website and sure enough he's in the group. I've never got a chance to talk to him though?
Closest real 4x4 trails are up around Shaver Lake, Dickey Creek area, Bald Mountain, Brewer Lake, Swap Lake, Dusy-Ershim trails. Bald Mountain trail is only one open in winter.
X2 ...Lots of trails up around Shaver Lake. I've run Brewer Lake and Bald Mountain in an essentially stock Wrangler. But there are much more difficult trails to keep you interested as the mod bug takes hold
Nothing too special...but here's some pics from our trip to the Tamarack SnoPark area (We ran the Brewer Lake, West Lake, & Bald Mnt trails):
