It all depends on what you driving, It is a challenging trail, but it is a fun short one also, fun to do just as the sun is setting too. The z-turn is a tough spot but if you choose the right line its not to bad. I have witnessed 3 roll overs on this trail and two were on the z turn, the other was on top. If you are bone stock, dont do it, if your lifted and locked, you shouldn't have a problem.
When are you going to be down, I will be down on the first weekend and have sat and sun open, if your down then I would be more than willing to go on that trail. My kids have been begging me all winter to take them on it-- Robert
PS make sure you stay on the trail. It is surrounded by a WSA and is threatened by suwa to be closed all the time
