There are a few airshows around this area also. My favorite is at Millville NJ airport which is adjacent to New Jersey Motorsports Park which is a fantastic roadracing track facility that I've driven on many times (track days). The airshow brings in all sorts of historic aircraft and the show includes a car show at the track which attracts a few hundred cars of all sorts. A couple years ago my favorite moment was when a B-17 buzzed overhead at very low altitude. A picture is worth a thousand words so here's a few from past shows:
