Good points, Nathan.
One area that we don't have enough data is whether the odds of capturing a BF in thermal imager increases by going deep in the wilderness (or as you say bushwhacking off trails) or just staying close to the campground (either on human trails, dirt roads, or game trails close to camp).
I did a brief (not comprehensive) study of these 5 videos to extract (at a high level) where and how they got these videos.
The table below is a summary and the links show where I got most of my information.
What is interesting is that all these 5 videos were taken close to the campgrounds or in private property. So nobody went deep into the wilderness or bushwhacking to get these videos.
My understanding is that 3 of these campgrounds (#2, #4, and #5) are not official NF campgrounds with facilities but just campgrounds that folks set up by pulling off a dirt road in a National Forest.
I suspect that in those 3 cases (#2, #4, and #5), the folks doing the research were by themselves and did not have strangers camping nearby - since the area was probably targeted as isolated and amenable to private research.
I don't know about the Torreya State Park and whether it has campground facilities (like picnic tables, bbq pit, toilet, running water) or if it is like the others (no facilities) or whether it has lots of visitors.
I think 4 of these were car-camping outings and not backpacks, so they drove there and camped close to cars.
Regardless, these 5 videos demonstrate that BF comes to you at your campground (or private property) and we don't need to go too deep into the wilderness (or bushwhack) to capture them.
Maybe if we set up a camp deep in the wilderness and make them come to us, we would have similar results, but not sure the extra effort is worth it if the odds are not known and we know already that BFs visit camps close to dirt roads.
I have gone backpacking deep into the wilderness with the belief that it will increase my odds of thermal capture, but maybe that is an assumption (still to be verified).
