When I was a kid we had a parade for our town's Sesquicentennial. They had tanks and soldiers marching and stuff; it was pretty cool. I seem to remember my father getting some movie footage of it, but I haven't seen it in ages.
They had a cool display set up at the high school before the parade. They had Nike missile launchers set up, they had tanks that they let the kids climb on (I remember climbing into an M7 Priest and elevating the barrel... ), they had a Rascal missile on a trailer, and there was a Navy F7U Cutlass that they trucked in, too.
I remember two F7Us flying over in formation, an H-21 helicopter doing a rescue demonstration at the Town Park, and a small arms demo including machine guns and a BAR at the park. There were a lot of displays inside the high school, as well. The parade was the high point, though. That was a long time ago, and I never saw another one quite like it.
