Here's some brief details for the website so people can get to the camping reservation page. I'm not sure on the specifics of getting from the campsite to the start line yet but I'm sure people will figure it out. Also, I'm not sure if the other camping areas are close to the hilton loop.. i'd assume they are in a similar area but you might know more about that.. feel free to edit and format however.. I'll have to keep this in mind and then I can work up some more details for next year.
