Just learned that all the National Parks banned drones and then discovered the ban actually started in 2014 with a blanket ban on all parks. But someone said the rule is you can't 'operate' in a National park, i.e. takeoff and land etc. but you can 'fly over a NatPark at higher altitude" (whatever that means). Anyone know the details of the current NatPark rules as of March 2016? Thanks!
