If you do just the Mojave Road, its pretty underwhelming. I just got back from a 4 day trip and it was pretty awesome. Im going again in Easter with the same guy that headed this trip. I do recommend going with someone knowledgeable like this guy from Toyota120 forum. He even has ties with park rangers and had keys to some of the trails. I took a billion pictures but i don't want to hijack the thread. Here's some of the awesome places not available on the road itself.
