It is the 30th anniversary and the paint does need a touch up. Do not underestimate the time required to go around Slick Rock. Carry lots of water. I was at first disappointed that motor vehicles where also present on the track. But they are clearly in the minority and I saw no conflicts between users.
Motorcycles are the main motorised users.
Most of the track is unsuitable for more than two wheels. It wasn't until after I had completed the track that I found out that the area was opened up by motorcyclists who first approached the authorities regarding creating a track in the area. It also explains why some of the route involves very steep slopes. Slick Rock is a good trail. And given the hype about it, if you come here, you have to ride it.
