While scanning a mail order catalogue I noticed for the first time the availability of digital game cameras that attach to a tree and can record images over days. Designed for hunters, I think it is only a matter of time before some new images of BF will be posted as a result of this technology. If they leave tracks and sign they can be photographed. Photos of similar animals from different people in different areas on different days ought to generate some interest from a National Geographic type sponser for a concerted effort at investigation and verification.
Very interesting site.
