Took my family to the Air Zoo at KAZO.
I'd only heard of the place before, I hadn't heard much about it, just knew it existed. I was impressed, and so were my wife and kids! They not only had lots of airplanes (including an SR-71, an F-117, and the only whole Waco CG-4A I've ever seen), they had some really cool engines like the P&W R-4360 Wasp Major (huge!), a J-58, and an early GE attempt at a jet engine that looks WAY different than anything you'll see today.
They also had a whole bunch of space stuff like Mercury and Gemini mockups, and some really cool engines from that side too, including a massive F-1 (Saturn V first stage) and a J-2 (2nd and 3rd stages).
But, the thing that really set them apart is that it's very family oriented. There are aviation-themed carnival type rides, video games, flight simulators, cockpit mockups, etc for the kids to ride, climb on, and play so that they have a positive experience. The gift shop is also one of the best we've seen.
They're also part of the Association of Science and Technology Centers, as is EAA, so if you're an EAA member and live >90 miles away, you get in for free. One of the best EAA member benefits IMO! We also got into the Museum of Science and Industry for free the other day, so the EAA membership definitely paid for itself this year. (Ahem, AOPA - You guys used to be this way too...)
Anyway - Looks like it's a bit over 1.1 hours away via Mooney, so I'm sure we'll be back at some point. Definitely recommend it if you get a chance to go.
