I did some looking at past threads on White Rim Road. I especially like this trail report, but it is 6 years old... http://www.sportsmobileforum.com/for...il-4384-4.html
We were hoping to do it in the wintertime and that never panned out. Now we are heading out there in a few weeks and I am doing some reading on the trail and one of the guides mentions Lathrop Canyon Trail to get down to the river over near Airport. It mentions a ledge that could be difficult to navigate on the way back up. It says that there is a bypass, but that the bypass has a very low overhanging tree, so not recommended for tall vehicles, er, SMB's.
I was wondering about the current conditions. Has anyone been there lately? If so is the ledge he is speaking about a tough obstacle, or is it pretty doable. We could always just park and hike down if it looks tough, but I thought I would ask.
