I dunno. The tin foil comment was just a first post grab

.
But honestly... i live near griffs and to me it seems theyve had more activity lately. Could be commercial training though. Id say they are drones..
. and i wouldnt put it past the marijuana hunt either... heck they busted that big crop near albany ny and man were they proud.. used several copters which are expensive. And who knowz how long they spent trying to find it in the first place..... like those senators who copter to work on our dime so they sont have to wait in traffic in limos...
