ummm.... you mean last year's show??
It was pretty good. Clearly AF-centric (duh), although sometimes there are good demos from the hornet/rhino/harrier teams.
IIRC, last year we had a little vietnam demo with Skyraiders, an AC-47, an OV-1, a huey, a MiG and I think there was an F-4... pretty cool.
It all really dymanic on the quality of the show year to year and it really depends on the number and diversity of both static displays and performances in the air.
I can't really tell you yes or no... I would like to think that you'd get a whole lot more out of your weekend if you also plan to see the sights here in vegas once the sun goes down.
On average, my rating would be 6.5 to 8.5 out of 10.
Best one was in '04, since the VF-101 Demo team was there. That year would probably rank an 11 for me.
