Saw on television tonight that Amazon wants to use unmanned drones to make package deliveries. I didn't know they were available as small as the prototype they demonstrated. A quick search for personally affordable drones show several designed to carry video cameras. For example: http://www.uavdirect.com/Phantom-UAV...-p/phantom.htm
Think of the possibilities:
Is there a moose in that valley?
Is that ram legal?
Where did that caribou herd go?
Where are the bison hiding?
Searching for river crossing
But there are probably laws against it.
