I happened upon a sign that said "Air Show Today" on the side of the road last year. It was by New Smyrna Airport. My buddy and I followed it to the side of the airport where it looks like they restore aircraft. The had a b16? bomber there, a couple of p-51 mustangs, a tank, and some other cool stuff. It was free
to get in, and you could walk right up and get in most of the planes! There were some vet's there with some cool stories too.
Edit- Here is the link to their website. Check out some of the current and past projects!
