Bortz... your pm mailbox is full so I'll post here.
This info is for Oregon Inlet and South as I know very little about the northern beaches.
Because of closures at some ramps due to birds and turtles, check the following link before you go. It has a breakdown of each ramp onto the beach and shows whats open and closed. The NPS updates this several times a week.
Make sure to air down. Take a recovery strap (no metal hooks) with loops and a shovel. If you start spinning,,,,,Stop or you'll dig yourself to the frame.
Ramp 38 is the worst for loose sand.
Also, double check, but I am most certain that NO night driving is allowed between the hours of 10:00 pm and 6:00 am until after September 15. This means no vehicles on the beach. You can be on the beach during these hours, but you must be a pedestrian. I think fires are allowed below the high tide line
Also, follow all standard traffic rules. Seatbelts must be worn (the NPS can and will ticket you). You can consume beer on the beach, but do not have open container in the vehicle. They can also ticket you for DWI so be careful. Speed limit is either 15 or 20 mph.
Let me know if you have more questions..........
