When someone can tell me what the minimum breeding population of bigfoots would have to be to be to have a sustainable population, I might be interested. When someone comes across a dead bigfoot carcass, ditto. When some elk hunter has a bigfoot in his crosshairs, ditto. There are only about 2,000 grizzly bears in the continental US and it isn't exactly hard to fine one. In January what does a 350lb bigfoot eat? Same with the Yeti. What do they eat in January in the Himalayas?
