The previous 47 excellent reviews were right on the money... Brandon's tour is indeed EXCELLENT. Rugged, heavy duty bikes were a breeze to ride and the terrain was fanatastic. As mentioned by almost every other review, Brandon's knowledge of the desert borders on encyclopedic. You'd be hard pressed to stump him with any desert related question. On top of that, he's very personal, ensuring our experience was unique, informative and fun. Highly recommended!!!
