At this point my field operations, report work and possible interactions in the state of Michigan { as well as some fellow researchers within my state } seem to point to consistent operation within a area that is suitable for habitation at least through out the warmer months.
I might add that I am planning a few winter projects in few new areas to try and get a better view of winter month movement or a lack there of.
In the case of finding a zone of consistent habitation I have found it almost completely based on the four factors of area size, forest composition, consistent food resources and the inability of human movement within the select area.
I am of the mind to believe the reason that past and most current efforts have failed or where/are not effective long enough to produce good evidence is because the underestimation of and lack of consideration of how the sasquatch may view us.
For instance, many researchers wear camo and stalk around through the forest trying to get that photo or track them to a bedding site, this s a rather predatory behavior we exhibit and is probably makes most researchers something to avoid.
My mix for sasquatch soup is to get deep into an area with all 4 factors I mentioned above and camp , sit around the fire with no other lights and make some odd noises like blow on a kazoo, bang on a metal washtub, bust up fire wood without an axe, make funny friendly sounding voices or anything strange. Be different than the average hunter or camper and be as considerate and nonthreatening as possible. We rarely do vocalizations and night hikes, we do most of out trekking in the day time looking for tracks and other passage evidence.
I think that to them we are a bore or a pain most of the time for them so we have to break that mold to get their attention and hold their curiosity. Through my own experience I am convinced this methodology works.
