Most low flying unmarked planes in NE are looking for pot plants/growing areas in the woods (stills too as well as questionable campsites/trailers in the woods that may be drug related)...that’s what our LEO friends tell us anyway....it’s a full time job and they have had a lot of success with it in NE-so I guess it’s Vermont’s turn!
Welcome to the War!
A huge C-130 looking for the elusive pot field? Possible, but I doubt it. Seems like over-kill to me. They would probably use a much smaller plane or one of the new fad drones to do the task much more efficiently.
