I know that Drone usage in National Parks is now illegal but has anyone seen anyone using drones or micro drones on sections of the trail that do not reside withing National Park boarders possibly to capture aerial pics and videos? I have a micro drone about 3.5 inches square with a 3.0mp camera on it and wanted to bring it in order to obtain some shots in the areas where its legal to use one. Just not really sure if anyone else is and what percentage of the trail is not on National P:ark land... if any at all.
