Aside from the fact that the park is very well maintained and there is an abundance of wildlife, you get pull through sites with full hook ups on the cheap! I have a State Parks Pass which makes it even more affordable. While we were there we saw an abundance of deer and bunnies, plus we were able to listen in on a conversation between a very large owl who had taken up residence in one of the trees by our site, and a long distance friend several sites down (judging by the difference in volume).
Add to this the little extras - a separate email from the park staff allowing me to go ahead and have them print my reservation and have it waiting for me - a great feature because we got on after the park office had closed, and you have a great experience. Love it and will be back very soon!!!
