I think that is going too far. Having a known hoaxer, as Marx is reputed to be, involved or even nearby should rightly raise red flags, but that's all they are, red flags, NOT proof of hoaxing any more than lack of such an individual in the area is proof of authenticity. A person doing honest and competent science investigating a report is going to be exactly as thorough without a "Marx in the woodpile" as they are with one present because to do any less is not doing their due diligence. If you consider his presence an indicator of "loud and clear" hoaxing, you're letting your emotions interfere ... not an indicator of doing good science. My opinion only of course.
I don't know what to think of the Bossburg tracks. I can't prove them authentic or hoax. The best data I have is interpretation, not raw info, presented by people who have already taken one side or the other of this issue. I can look at photos but they're not that great. I can't go back in time, see for myself, examine for the things that might have been missed, examine to address questions raised later. Best I can do for now is stack them in a very large "hmmmm" box. Costs me nothing, gains me nothing.
