Camping at the State Park is a lot of fun. It's cheap, close to the water, and best of all- they have showers.
They allow dogs, as long as you keep them leashed. So spark of the campfire, tie the dog to the picnic table, and start telling some scary stories!
They take reservations six months in advance, and it's best to book as early as you can.
This year we waited too long to get a site (4 months in advance).
