I can't say enough about the Sugoi Dirt Series women mtb camps. Unfortunately I think they are mostly held on the west coast. But if you can go, do it. I learned so much this past spring over one weekend and plan on hitting the co'ed Whistler one next fall with the BF.

Do not be too timid and squeamish about your actions. All life is an experiement. The more experiments you make the better. What if they are a little coarse, and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice? Up, again, you shall never be so afraid of a tumble.
