^^^^ That is likely partially true. I think it overlooks a couple things. One may just be specific to my location, the other to trail cams in general.
1) The concept of home range does not apply here, it's not a tiny little space. The area where I have the most activity in late summer is under 7 - 10 feet of snow right now, maybe more. There are no deer, no bear, no elk. Nothing really for a bigfoot to eat, not on an appropriate scale. There are likely a few coyotes and bobcats, cougar, and wolves passing through and there may be enough small mammals like rabbits for snacks to tide them over. They're not living there but the snow has settled enough now to be dense enough to support their weight. Not a bigfoot. Probably not a person quite yet, not without snow shoes, but as spring progresses, the snow pack will settle, get denser, ice up, and eventually we'll be able to walk on top of it. If I'm correct calculating that bigfoot has about 4x the weight per square inch of foot, it may never support a bigfoot's weight, they have to step clear through to the ground. Anyway, home range varies seasonally and likely is 30 or more miles across. That's how far you have to go to reach valley bottom where the food critters spend the winter.
2) Regarding trail cameras, I've been pondering what I've observed so far. I don't think most of those cameras out there have any benefit to the search for bigfoot. The bigfoot tracks I've found are not precisely where I'd aim the cameras intending to get pictures of normal game animals like deer, bear, cougar, and elk. This suggests to me that the more skilled the camera operator is regarding hunting normal critters, the less likely that person is to get a bigfoot on camera on accident, such a person has a better chance of getting a bigfoot picture but only if that's specifically what they're trying to do. How many of the millions of trail cams out there are actually targeting bigfoot?
