I've been a half dozen times as well. Graduations certainly screw up more trips though. This year I have 2 graduations to go to so it isn't going to work out for me this year.
MAAM puts on a great show and has a LOT of warbirds. Not just the one or two you see at other shows, but closer to 20, and they all take a turn in the air show. Stage shows, battle reenactments, guest speakers and some great food all long side one of the biggest WWII flea markets you can see. It's a great time for anyone into WWII history even the littlest bit.
.....oh and yes REDBULL it's at the Reading, PA airport.
