I went fly fishing in Norther California last year and during a break I flew the drone over some fly fisherman after asking permission. I went back this year and went to fly in the same area and DJI GEO fence is in place and asked for my phone number to ask permission to fly except there's no cell reception in any of the are I wanted to fly
the only thing I can figure is the area is also home to PG&E power plants and homeland security decided it was protected infrastructure! I'm thinking that will become more prevalent!
