ExpoGeorgia is the king of understatement. What "got stuck" really means is I went down the slope first, started sliding, and then with the assistance of a medium-size shrub, finally stopped, sideways, on the trail. It's kind of a blur now, but I think the sequence from that point forward was: try to get straightened up, slide down the trail backward; try to go back up, slide down the trail backwards again; drive up on the edge of the trail (over several pine saplings), slide backwards a little, to a final stop.
What "[e]ventually" means is: at my request, we spent about three exhausting hours slipping up and down the slope, as the temperature dropped and the wind picked up, to move my cruiser about 15 feet, using my recovery strap, a tow chain, and my hi-lift jack. When we couldn't reach the next tree, I finally admitted that it was time to try and call for help. Expo had stopped on a small ledge toward the top of the incline, where he thought he could easily turn around and drive back up the trail. That is, until he tried to turn around and drive back up the trail.
So, we walked up the trail instead until Expo's girlfriend's phone had a signal (our phones were useless), and I started calling everyone I could think of, including people in Georgia Offroad Ministries (formerly Georgia Jeepers). They have an Emergency Response Team (ERT), and a couple of hours later help arrived.
The yellow arrow is Jeep#1, which was anchored to a tree with a recovery strap. Jeep #1 has his winch cable attached to Jeep#2. Jeep#2 has his winch cable attached to Expo's Lexus.

I was too far down for a cable and straps to reach from the top. So, the plan was that Jeep#2, a JK with one-ton axles, lockers, and 40" tires, was going to come down to me. Then, he'd turn around, I'd strap up to him, and he'd winch both of us back up. However, they wanted me to back (slide) all the way to the bottom just in case Jeep#2 started sliding on the way down.
The last thing I wanted to do was tempt fate with a 3rd backward trip down the trail, but it ended up being my smoothest one of the day. When Jeep#2 started down, he didn't go more than 15' before he started sliding. He slid past where I would have been if I hadn't moved, but was able to stop without hitting me at the bottom. He turned around, and then we both drove as far back up the trail as we could, which wasn't very far. From there we strapped up and he had to do five full pulls with his 75' winch cable to get up to where we finally had real traction.
Close-up
As is always the case, the angle was steeper than it appears in the photos. However, the real factor that day was the slickness of the dirt. If you stepped on bare tire rut (no leaves, sticks, etc.), your feet would slip. Period.
