Let me get this straight.
You're hunting for Bigfoot in the area of Wetappo Creek, Florida. This area (according to Google Maps) has a public road every mile or two, and even more roads that look like logging roads. The whole area has been mowed flat and re-planted with tree plantations---it's not Pacific Northwest virgin forest. It has a population density of 23 people per square mile. It's bisected by the well-used Intracoastal Waterway; it's not far from a 3000-person Air Force Base and from cities like Panama City (pop 30,000). Your local Bigfoot doesn't have a single place in Gulf County where it can walk a straight mile without crossing a road. It doesn't have a single place where it can explore a square mile of non-plantation forest. It doesn't have a single place to ramble over 10 square miles without finding a house.
If you're going to imagine an undiscovered (except by you) Bigfoot in this area, you're basically imagining that this Bigfoot has an incredible ability to avoid roads, cities, towns, house, trailers, cars, recreational boats, commercial boats, airplanes, fishermen, hunters, foresters, and loggers. You have to imagine that Bigfoot does this, because otherwise Bigfoot photos would be as common as, e.g., Florida panther photos. Which they aren't.
What makes you think that this sort of Bigfoot won't hide from a motorboat with a 12-foot manned watchtower on it?
