What a great opportunity to learn. Funny how we figure things out and become good problem solvers when out in the "Piney Woods." I camped in that park on the way back from paddling the Boise Brule River in NW Wisconsin about 15 years ago. It was pretty. Good luck with the tarp. Part of the fun of hanging is it is a dynamic event. Always changing, always evolving.
The World is my country, all mankind are my brethren, and to do good is my religion.
