Clancy,
Call to AAW office on the toll-free number and ask. I think there were a number of tickets distributed to chapters, but you may be able to get one direct from the office if you're not going to St. Paul. Notice in the April Journal states tickets available "through your local chapter or in person at the Symposium."
Looks like those are your choices, Clancy, but if neither works for you, I'd call the office anyway. Best bet would be Linda Ferber as the Program Director.
