The Jones Beach Air Show is May 26-27 from 10am to 3pm. Cost is $10 for parking and admission is free. Features the US Navy Blue Angels, Golden Knights, F-22 Raptor, 106th Air National Guard Rescue Wing, Royal Canadian Air Force Snowbirds.
Get there early. In the past, this show has easily seen 200,000 people fill up the beach on a single day. It is not unusual for the parking lots to be filled by 11:00am (if not earlier). When this happens, the parkways are closed and people are turned away. So, it is probably a good idea to arrive before 10:00am, or as early as reasonably possible.
