I searched the forums for this area but didn't find anything, though the threads regarding the Gila River Airport are close. I'd like to try flying over the "mountains" just south of the Phoenix area, east of I-10 (almost directly south of Sacaton). The area is on Gila River Reservation land but shows as no restrictions on Know Before You Fly. Here is a screenshot of the location as shown on that website. I believe I am legally allowed to fly there. Am I correct?
