IMO, asking this question on an open forum is far worse than asking for fishing spots.. Well... The answers are the problem, not the question.
Not to sound like a sap. But a nice crown land campsite is a precious thing. Specially within 2 hours of the big stink.
I can only think or a dozen or so. But they where found through lots of research and ground pounding. I'd tell you where they where. But because of the good old Internet, you need to show up a day before the long weekend to get a spot.
