So, possibilities seem to be:
the track ways are faked (this does not pass the smell test for remote track ways),
the witnesses are lying (a possibility, but that means there are multiple liars reporting track ways, and perhaps providing photographs),
the tracks have been misidentified, or
they are real, and they need to be explained as being generated by a real non-human creature.
Merely asserting some explanation for a track is insufficient. The onus of proof for any proposed explanation is at least as strong for the skeptical position as it is for the proponent position.
Some people believe that the default position is to provisionally accept the report from an informant. I would not go that far, but when we have multiple similar reports, we should perhaps consider the consistency worthy of note as well.
This track way evidence should be compelling to anybody. However for some, perhaps those with an agenda, it seems easy to ignore. We have the odd flaky sort of rebuttal to this sort of evidence, such as scaffolding, weighted feet, people pulled behind trucks, and so on. Many of you have seen this stuff I am sure. People posting such absurd ideas should be put on ignore, they give skepticism a bad name. In my own view, we give them a credence they don't deserve by responding.
