Just got home. This place is a lot of fun. For the first weekend being re-opened there were a lot of people. Plus rangers were not charging admission.
There must have been 2 large Jeep groups there. I saw 2 groups of about 15 Jeeps.
I spend about 5 hours driving and I did not come close to covering 1/2 of the terrain. I missed out on a lot of the black diamond 4x4 trails because I was with a friend driving a 2wd. I saw a group of Jeeps attempting to go up the 4x4 "Look Out trail" and one jeep got stuck at a very steep part. As we were leaving the rangers were about to go help them.
Here is the trail that took us about 2.5 hours.
Later we talked with the rangers and they said that a gate should have been locked (where the map has a "B"). But we did not know so we kept going and by the time we had passed Bouquet Resivior and we were over looking Lancaster we realized we had to turn back.
