AZ State Parks & Trails has a prohibition of drones within the state parks with the exception of commercial photography access by permission, etc (mine flight would not be 107). I wrote to the manager of the department and included a link to the FAA Press Release - "FAA Statement–Federal vs. Local Drone Authority". I told him that the State Parks & Recs blanket prohibition was in contravention to the Federal laws issued by the FAA which is the singular regulator authority governing all activities within the National Airspace. I also gave him more info on Congress's FAA Reauthorization Act which gave the FAA sole authority over regulations concerning UAV flight rules, UAV registration and pilot certification. Bottomline...he wrote back and said he had his staff investigating and I should follow the Park regulations. I made one last stab and suggested that, at a minimum, he should suspend enforcement until he has completed his staff's investigation and that I intended to safety exercise the privileges afforded me by the FAA within the National Airspace and would contest any citation issued. AM I WRONG? Let me add that I would not fly my drone within a sate park where there was considerable visitor traffic or within a limited geo area surrounding a monument, etc. However, AZ has thousand of acres that are "Stare Parks & Trails" in remote areas. I wanted to take the moderately difficult rocky trail to the site where 21 Hot Shots lost their lives in a wild fire. The entire 12 mile rocky hike (1,500' ascent) is included in the designated memorial state park. I can assure you, there are very few people making this 4-hour hike.
