Yes, big time racing does visit the tri-state area. But, you need to know where to look.
Below is a list of the major tracks in the area and links to their websites. Let this be your first stop when you want to go see some serious racing cars in person.
Pocono Raceway is an oval, but it has 3 road courses that use parts of the oval, and they just spend a lot of money to upgrade everything.
It hosts two NASCAR races and the IndyCar series has made a return after being away since 1989. Both series put on great shows.
SCCA runs here a lot, and the Bertil Roos F2000 racing school is based here.
