Marc:

Go back thru Google groups for threads about camping at OSH. Jay, of
course, is the Resident Grand Master of camping there. He can offer
a very large number of suggestions that you should take as gospel
and believe every one of them if you're going to camp.

As for spot landings -- that's less of a problem than the realization
that there are airplanes *really close* and I mean REALLY CLOSE TO YOU
as you come in over RIPON and thru the entire approach and landing.
