There might be another way:
Using radio controlled things doesn´t seem to work. So you have to use a cable-bound control system to control it. 3 Miles of cable should have quite
some weight, so the way i suggest is this:
Get some radio controlled model car with a powerful engine and connect the servos with your cable. Add some kind of a camera and connect it to the
cable too. The cable is connected with a device for the steering of the car and with a notebook for recording the video. Record the video on a small
storage device (perfect would be something so small you could swallow it if you are searched by the cammo dudes).
For the next time, do not start your vehicle right at the groom lake road, find some place at the border where the cammo dudes wouldn´t see you right
away. Start the car and steer it into the forbidden area. Use your camera to see where are you going and make regular turns right and left to see if
any dudes are around. If the dudes have seen the vehicle (camouflage painting of the vehicle might help), try to outmaneuver them (that vehicles are
unbelievably maneuverable). If you see the cammos heading in your own direction, cut the wire and get the hell out of there - forget about the car. If
you really hate the cammo dudes, you could also add some explosives to the car and press the button when they have catched it
Good luck!
