The man and woman got out of the vehicle and walked north toward the point and the male looked to be carrying a camera. No beach driving permit either.
This is obviously a NC state government operated vehicle and highly likely that the NPS allowed permission for its use at CHNS. NPS follows NC state protocols for nesting shorebirds and sea turtle's and there is mutual cooperation between federal and state resource management.
Surely if you got a ORV permit you read the FAQ sheet given to you.
"24. Why do I sometimes see ORVs in
areas closed to ORVs? In addition to
NPS vehicles being used by NPS employ-

activities and emergency response ve-

areas closed to ORVs only for very specific purposes"
You could have easily nicely questioned any NPS personnel about its use, sooooo why didn't you to satisfy your concerns?
