If you live in southern California the Mojave Trail should definitely be added to your to-do list. I have only done it twice driving from an exit off of Hwy 15 north-east of Barstow and took the trail to Laughlin NV. Both were day trips and a great time, but I would like to spend a few days out there exploring and camping. There are so many trails and landmarks to explore.
There is a great website with allot of info, maps and GPS files if you ever plan on making the trip. These photos are from a few weeks ago when a few friends and I took the trail on our way to the SNORE Rage at the River desert race. And from a trip a couple years ago that I took with the Total Chaos Fabrication crew.
