I contemplated both of these rides, but I don't think I'll be able to make it. If my fortunes improve, I may sign up late. A friend of mine mentioned that she and a few friends were contemplating Cactus Hugger. I told her about te so hopefully she will post soon and maybe you will have some riding buddies.
Have you joined any of the Wasatch Women's cycling club rides? They always seem to be out and about riding and joining these events.
If you don't mind a slow newbie rider, I'll probably ride the Ghost Town Century in April...although I don't know if I'll be ready for the full century by then, but I will do as much as I can.
