Me and my buddy are pretty certain we are coming for the 1st time...Would there be any more space available for me and my friend to tent? We are coming with another friend in an RV, but all the spots are taken for sleeping. I hope I'm in the right forum for this. And also, what would the cost of joining a group be?(the $35?) Also, would there be any more costs to rent space or anything. Sorry for the not so smart questions, just want smart answers! Thanks!
