Around New York, there are a few places they pretty routinely lose
radar contact if you're down low (around Madison VOR and out near
Huegenot). It doesn't seem to bother them one bit.
PTA-whatever-it-is? Feh, they just ask you to report the next
waypoint and everybody's happy.

Millville has an approach that's non-RADAR. Where else?
