AirVenture
The EAA Museum is located in Oshkosh, Wisconsin and I am lucky enough to have attended the annual AirVenture event featured in this video a number of times. Anyone who likes airplanes, history, aviation, etc. should attend, it is totally epic. In addition to the regular museum exhibits (a variety of planes, gliders, jets, plane parts, and a flight simulator), there are multiple air shows during the six days of the event, helicopter/plane rides, literally hundreds of vendor stalls and tons of family activities (younger kids can make cardboard rockets and rubber-band powered balsa planes; older kids can make a wooden plane prop replica or try riveting).
While at AirVenture, I got to fly for the first time (on a helicopter, still haven't been on a plane), I got to see a B-17G Flying Fortress
in flight (got to see it take off and everything!), also got to see a B-25 and a C-5 Galaxy, Blue Angels F-18, F-22 Raptor, AV-8B Harrier and too many warbirds to count.
More information on AirVenture can be found here, with video of last year's AirVenture:

I always liked old planes, especially World War II ones. As a kid my favorite computer games were Fighter Ace and Pearl Harbor Zero Hour. My dad and I used to argue over whether the P-38 Lightening or the P-51 Mustang was better, lol.
