Hi Cotter -
I dunno. I've thought about it some (a lot). No answers, but the speculation runs sort of like this:
Picking the question apart, considering our move towards imbedding processors in biological organisms and possible biological computers in the future, I think the question of whether it is "just by thinking vs using equipment" stops having any meaning. Paradigm shift. Further, string theory seems to suggest that point to point transfer is possible, at least mathematically. (My perception of "dimensions" is that of a physicist, not the "woo" interpretation. Dimensions are measures, not places.) It really comes down to engineering. We're a long ways from having the engineering moxie to build a device that would facilitate a dimensional shift. Whether a living organism could survive such an event, even if such a device existed, who knows? A final thought ... would we recognize such technology? It seems so far ahead of us that Arthur C Clarke's famous quote is applicable: "any sufficiently advanced technology is indistinguishable from magic."
Even if they were able to do all that, and I think it's a big if, I don't think it would stop them from being shot in all cases. You have to be aware of a danger before you can act to avoid it. Yes, I do put stock in SOME OF the stories of BF being shot. Compared to other types of reports, many more of these ring false, but some do ring true.
Finally, no, I don't think BF uses anything interdimensional to avoid trail cameras. I think the answer is much simpler strictly based on simple F&B.
