If I remember correctly people did a really good job with this last year. I sure hope it is the same this year. They are incredibly generous to let us use their beautiful property for this event. Everyone should leave it as clean (or cleaner) than they found it.
As I remember last year, the camping spots were sections along the field with enough space for a mediocre tent, but you had the whole section all the way back to the "road" (plenty of room) to yourself.
