It's not too early for the Burning Man fundraisers. You can eat spaghetti and watch spaghetti westerns to help benefit the Kooshpeople. You can also help out the Rope Bondage camp by attending their well known Tie Me Up! event.
A friend of mine attended the latter event last year and took the rope bondage class. She recommends the class for just about anyone and was impressed with some of the feats of The Knotty Boys.
