I've come across numerous game cams that have a flash at night (I hunt coyotes at all hours of the night) and I rarely get scared and run off... I usually drop my pants and moon te camera actually
They make cams with nighht vision nowadays... no flash, and a well hidden/camo'd cam = no one even knows its there...
LOL! That would send me runnin for the hills
Seriously tho... it makes no difference if its your property or not. someone obviously knows, and what're ya gonna do... shoot them? Fuck that shit, a few plants or lbs of weed aint worth doin time over...
Find a new spot, and TELL NO ONE!
All that being said.... I live in a medical state, and now have the legal righht to provide myself with my medicine. So I put a fence around it, with a locked gate, and a shitload of game cams. If someone steals my shit, I call the state police, and hand ove the pix from the cam... let them do the dirty work. The state police takes theft of presciption drugs very seriously here, and whether it be weed or oxy's, they treat it the same, as long as I'm within the confines of the law.... Hence the fence & locking gate....
