Havelock, NC 28533
You must enter through the Main Gate off Roosevelt Ave. The guards will likely give you a placard for the Autox. On the back of that is a map to the event site.
Just in case, once on base continue on the main road until you pass the flightline (hard to miss no trees speed limit picks up and there is a sign). Past the flightline there is a stop light, turn right and it is your last right just after Duffy Road and before the T intersection that end of the road.
There is usually a sign at the stoplight and just before the turn in to the flight line that say AUTO-X and an arrow.
