Can you describe just how newbie you are? Both sound fun, and I did a women's mtn biking day lesson/camp not too long ago, and it was awesome. Really boosted my confidence, and learning in the company of women was terrific. If the road ride has been around, and will continue to be around for future years, I would do the camp, because it may benefit you more at this point in the game by boosting confidence and building skillz. I guess I would just think about which one would inspire me more!
