We'll be there with a group of about 16 along with about a few thousand other people for the 4th. The fireworks display is always pretty good, but the riding conditions will be horrible the entire weekend. If you're lucky you might get some good water early in the morning and just before sunset.
We're heading up on Thursday morning so we can hopefully get a good days riding in before the weekend crowd arrives. As for the rest of the weekend it will be relaxing and partying with good friends, probably by the waterfall at least one of the days.
