Thanks everyone.
Champoeg, at last call, is full.
Columbia Riverfront gets a bunch of poor ratings and a bunch of good ones. Poor mostly for noise.. and some undesirable's. But, a LOT of people, both here and the other forum recommend it.. so, we'll make a point of trying a reservation tomorrow.
Other state parks in the area don't seem to take reservations...
Onward.. thanks again.. Bill
