TSCC doesn't have directions to Pungo, they race at ACU4
Pungo is at the old Pungo airfield in VA Beach. The entrance to the part used for motorsports (the old aircraft apron- presently the largest piece of concrete there) is off Princess Anne a few hundred yards north of Indian River Rd (and Pungo Offroad). The Coast Guard has some really tall antennas on the other side of the old airfield that you can see from pretty far away.

It's pretty easy to get to. Make sure to keep your eyes peeled for the entrance, though, it sneaks up on you!
