Lostlake does have camping not sure of the price, young crowd great party. As for other places to stay I'm not to sure. I stay up river at Big River about a 20 min. boat ride. They dont have tent camping, but it's a great family camp ground.
I will also be there of the races on Sat. night. Let mw know if your going to be there, alway like meeting others from the boad.
