I don't have the 2011 dates yet, but if you enjoy WW2 nose art, there's an event worth visiting in Midland, Texas every fall -- AIRSHO.

I spent Saturday at the latest one. Still a little footsore and a lot sunburnt.
It kicked off with F-16 flybys and finished up 4 1/2 hours later with a missing man formation of warbirds. In between we saw aircraft re-enact Pearl Harbor, 30 Seconds over Tokyo, Ploesti, Dresden ... and Hiroshima. Yes, the B-29 flew over Midland for AIRSHO this year. There's only one flying-shape B-29 Superfortress in the world. It lives at the CAF hangar in Midland, and it's going on a national tour called Red White and Loud this coming year with Aaron Tippin.
We saw a Strike Eagle demo and a B-1-B Lancer (aka Bone) demo, and a C-17 heritage flight side-by-side with a C-47 from WWII. We saw a jetpowered sailplane and a twin Beech and a highly-modified WACO, and we listened to Pratt & Whitneys, Rolls Royce Merlins, and every imaginable variation of aircraft engine in between, and there were *explosions* too ... oh, and Johnny Rutherford exhibiting a Chapparal race car.
It's like a cross between a county fair, an airbase open house, and a military history buffs' trade show.
The nearest Texas State Park is at Monahans (aka the Sandhills).
It's a pretty awesome place, but one thing it's *not* this time of year is, necessarily, "cool". Although the nights are balmy.
