This is what bothers me. First, FWIW, I made a chart for my own edification comparing biological facts about common animals. As I got all of this information off the web, I am certain that it is highly accurate & not subject to question. Somewhere, I found an estimate that Cro-Magnon, Neaderthals, and paleo-Indians required 4,800 calories per day and moose required 9,700 calories per day. The data I found for other large animals is just in poundage - 10-20 pounds of food per day for elk, 30 pounds per day for grizzly bears, 35 pounds for black bears(?), and 30-45 pounds for gorillas.
What bothers me is that if Bigfoot is an omnivore, and if Bigfoot is as populous in the eastern US as some believe, why aren't they eating farmers out of house and home? Deer do it, groundhogs do it, foxes and coyotes prey on chickens, and such ... why wouldn't a bigfoot settle down near a nice big corn or potato or squash field and simply strip mine it for a day or two, then move on. That problem occurs with other biological animals, why doesn't it occur with Bigfoot?
