And here's the location: Lindbergh Blvd just before the entrance to Nassau Coliseum. Public park on one side, Hofstra University on the other, an bit of an old exit ramp to park and hang out on (illegally) and watch your buddies, and it's a one-way street with not much traffic at times, so they probably could look for breaks in the traffic to do stunts.
Lots of idiots hang out there and do stunts on the exit ramp when it's not crowded.
I like how a PI lawyer inserted himself into the map at exactly that location. Interesting form of advertising.
