FFS,,,,,,,,,,, You could mount an ultra light tranquilizer gun on the drone, and once found,,,,, shoot the oinkers with it.
Then,,,,,,,,,, by the time you "stalk" in they'll be easy targets that will give you plenty of chances to reload,,,,,
And fire again, and again, and again, and again, and again, and again,, (get the picture? ?
I do not fear death itself... Only its inopportune timing!
I've come to realize that,,,,, the two most loving, loyal, and trustworthy females in my entire life were both canines.
