I would love to go but after hearing that shorter wheelbase do better I fear for my LJ....
I did in my TJ that is 108. Your LJ will do great. The longer wheelbase will help a lot on the last waterfall.
My family and I did this trail on Memorial Day. What a nightmare. The trail was great, even though it rained most of the day. Mud sucks, but it was still fun. The nightmare came in the form of Tom's (land owner) employee named Carl. I talked with Tom back and forth the week leading up to Memorial Day, and he granted our group permission to park on his land near the trail head and cross his land on the way out so we didn't have to turn around. At the Maverik in town prior to running the trail, we were talking to several locals who said not to bother parking on the west side of the gate and that we'd be better of parking on the side of the road east of the gate on the county right of way. Sounded good to me, so that's what we did. Then proceeded to stay on all roads and travel across Tom's land to get to the trailhead. No harm no foul.
However, when we were finished with the trail and headed back to our tow rigs, Carl was parked on the county road and wouldn't let us pass to get to our tow rigs without stopping us. He gave me a huge story about how our rigs were parked illegally on private land and that he could have us arrested. I proceeded to tell him about my experience with the locals in the gas station and that that is in-fact county land and he couldn't do anything about it. And even if it was Tom's land, I had talked with him and gotten permission to park on his land and drive across it. And had text messages to prove it. His story changed a little at that point and said that had created a bunch of problems for him and Tom and that it still wasn't legal. Long story short, this is the 2nd time this guy has harassed my group when running this trail. From now on, there is no way that I will ever park anywhere near the trailhead. I'll probably park my tow rig on the side of the road just west of Maverik where it is super side. I'll still get permission from Tom to drive on his land, but I'm really sick of dealing with his employee that isn't in the loop with what is going on.
