Let me see if I have time to drive up there this weekend. I can see how easy it is to find and get around. They most likely give you a map when you enter. Since so many of us are coming from far away, we'll probably all not get there at exactly 11:00. Maybe we can pick one of the beaches to meet at.

Here's the map of the park:
