Just looking at the NW EAA's roster for their fly-in and airshow at Arlington WA this weekend (July 7-10) and saw that the Cascade Warbirds are not listed. Paul Allen's warbird collection will be open to the public for 4 hours each day but there is no mention of them flying. The military vehicles collectors association is not listed either. The warbirds typically did a mass launch with more than a hundred fly-by's, followed by a combined aircraft/military vehicle parade down the central taxiway.
So it looks like a rather quiet show this year for a $15 per person per day admission fee.
