Every wednesday night from April to October, there is a huge car and bike show at Bear Mountain Inn, along the Hudson River. There are between 700 to 1000 cars and as many motorcycles. Vendors etc are also there. No charge except last show of the season.(money goes to charity). Many, many Vettes (including a Grand Sport replic.) From 1953 to 2003....

I've been over there a few times & yes it's a great time. Much bigger than I expected. Saturday nights at Marcus Dairy in Danbury, CT (exit 3 off I-84) are also great fun with lots of great cars.
