ABP - Awesome re: Wellsboro. I had a number of survey sites for my doctoral work in that area. BTW, I once found a wadded-up pair of pantyhose way off on one of the seemingly wilderness trails in the PA Grand Canyon area.
Jodie, the issue is not where people
live and it's not even really where they
go. It's what they
do when they get there. If you want to really understand why people like me are convinced that there is not now and never has been a "bigfoot" in North America, you need to look at things like historical and current ranges for our charismatic megafauna (and some mesofauna). Consider over how much land area our forbears extirpated bison, moose, elk, deer, wolf, black bear, grizzly bear, mountain lion, beaver, fisher, otter, turkey, trumpeter swan, whooping crane, heath hen, passenger pigeon, etc.
Before there were McDonald's dotted across the landscape, before there were laws establishing rules for hunting . . . people derived their sustenance from the wild animals that lived in the places they could access on horseback or on foot. They shot everything, largely because they had to. Once we had some game laws established by the early 1900s (in response to the hunting to extinction of several species in the 1800s), those laws included bounties for anything that might be remotely tempted to steal a free-range chicken. That meant that people went out to the very last wildernesses for the expressed purpose of finding and killing the last mountain lion, wolf, or goshawk.
Imagine
this:
"Pennsylvania, more populated than the states ahead of it in the per-capita rankings, led with the highest number of deer collisions. State Farm estimated a total of 101,299 deer-vs.-car incidents in Pennsylvania in the second half of 2010 and the first half of 2011, the time period examined in the most recent iteration of State Farm's annual study. No other state reached six digits."
Now consider that by the early 1900s,
Pennsylvania was actually importing deer from other states (mostly from Michigan if memory serves) to augment the severely decreased population in the Keystone State. Can you imagine a Pennsylvania so logged and defaunated that its forest cover statewide was only about 25%, and white-tailed deer was functionally extinct?
This is our history of settlement of North America since the Colonial Era. There are similar stories of wildlife exploitation from all over the US and temperate Canada. The reason Yellowstone NP is special (and even it has dealt with species loss) is because it retains the species that everywhere else we hunted out.
So just because there isn't a Starbucks on the corner, or the cell phone reception is a bit spotty, or the roads are basically impassable for a good part of the year does NOT mean that such "wilderness" areas are unaffected by the comings and goings of modern humans. That's the first and most obvious fallacy with the "most of the world is land area where humans never go, so bigfoots could live there" meme.
The second fallacy related to that meme is that - by their own distribution built from those hundreds of anecdotal accounts that prove the existence of bigfoot to so many 'footers - the distribution of bigfoots is by no means restricted to areas of wilderness where people seldom go. Using the BFRO sightings database, it's quite obvious that such creatures are reported from a gradient of development ranging from wilderness to suburban. I'd classify the vast majority of that distribution as "rural".
