Someone somewhere told my dad that they use a standard size propane tank and bury it in the ground. They crack the valve just barely. The bears smell the propane and come in supposedly.
Now I know bears like to chew on rafts, gas cans, planes, and seems like whatever has petroleum products in it or made from it. I am not sure who told him, but believe they use this method. Will try and remember to ask today.
Just curious if anyone has tries such a thing. Never had problems getting bears to bait. This has always made me wonder. So figured I would here first. What do all you think?
