As someone mentioned in a PM, the P3S doesn't support an authorization zone. The other models also have a restricted zone, it's just covered up on the map by the authorization zone.
The good news is I'm there now and am able to fly the my P3S. I contacted the Wright Brothers Memorial Museum and asked to speak to the aviation authority. I was transferred to the Nation Parks Service and was able to speak with the Chief Ranger with the authority over that airstrip. Through email, he granted me permission to fly within 0.25 mi of the airstrip. I went to the DJI self-service unlock site and uploaded a PDF of his email. Within 20 minutes, they granted my unlock request for the week. I was able to use it last night. I had to use my wife's iPhone, because you can't unlock a P3S controller over Android. But it worked.
