I was hiking up in Alaska once and did happen across grizzly tracks and I don't mind telling you those were enough to send my sphincter into knots, so wounding a Bigfoot then trying to take him alive just left a pucker mark in my chair.
I have all ways hated trapping. It is very in humane, and just wrong. That is why I went with the pit idea. Although, the noose idea sounds good. But, wouldn't a noose tear through a animals skin trying to get out?
