4-wheel low in 2nd gear, get a good amount of speed and start the probably 80 degree incline. It's been super dry so it's all loose gravel. Get about halfway up and lose traction. F*#K! This is bad. The trail up is too narrow to turn around and the drop off on either side is about 500 - 650 feet depending on which side you tumble down. While not an experienced wheeler, I've run my fair share of trails. Frank Raines has some elevation though. Plus, I've got issues with heights.
Completely ruined my day out there. Bailed early on some other buddies that were out wheeling. I felt bad but I just couldn't shake the bad feeling I had after almost tumbling down the mountain.
(Stock YJ suspension on 31" tires)
Haven't been that scared in awhile guys.
Just remember to be safe on the trails, I know a lot of folks don't talk about that aspect.
