I have been to the LBL area on my own several times. There are a lot of Forest Service roads to run in the LBL as well. I have not done the Jeep Jamboree there but have attended 3 at Moab and 1 at Ouray, CO. I like the Jamborees. Stress free, meet a lot of new friends, a good time for about the same price as two days at a professional sports venue. We are going to the Black Hills Jamboree this year.
So, you will enjoy the LBL area alone or with the group. The Jamborees are a lot of fun. Just whatever you decide. I do not think you will be dissapointed.
