Bigfooter/prospector, Bob Barrett from Texas, US swears a laser pointer once saved his life.
He pissed off a big boy in the Big Thicket one night, as it charged him his first reaction was to dazzle his eyes with the laser pointer on his goggles.. Needless to say, it stopped him in its 15 ft away which gave him and his son time to back off. From what I gather, theres a lot of aggro big foot in the Big Thicket, and this one was every bit of 9ft.
Its been probably been brought up already, but a laser pointer maybe a worth while investment..
