In an article I wrote that's resting in the in-box of a BF NL, "Let's Firm Up Existing Evidence," I suggested that one important step BF buffs could take to make their case more believable, especially to skeptics, would be to obtain and post or print official facsimile copies of all BF reports by cops to their offices.  (These are public documents, I believe.)  Sort of like the facsimile documents posted on the Smoking Gun site.  I wrote, "Skeptics will accept nothing less."  (I.e., all the rest is just hearsay as far as they're concerned.)  Thanks for proving my point.

However, your remark, "no nothing except a story" is too dismissive.  There are stories and there are stories.  A story told by a single Bigfoot buff has low credibility--he's predisposed to seeing things, and maybe saying things.  A story told by multiple witnesses, all previously uninterested in the topic, some of them strangers, some of them cops (i.e., high-presumptive-veracity witnesses), and supported by a dent in a car, has at least ten times the evidentiary "weight," as it would require very unusual planning to hoax such a concatenation of testimony.  (Of course, as I said, to really make an impact, it has to be gotten "on the record."  Those cops have to be located and their stories tape recorded (ideally video-recorded), etc.) 

This is where there is a great opportunity for a TV producer to create a ground-breaking show (no one has focused exclusively on cops before), and to obtain a wonderful publicity teaser for it.  "Now revealed for the first time:  Cops Speak Out About Their Encounters with Monsters"!

EDIT:  Here's a catchier title:  "Face-to-Face: Flatfeet and Bigfeet!"

Can't remeber where I heard about this but the sighting goes something like:

A guy as driving down a highway road and hit "a man a fur coat" (I think it might have been summer too, not sure) Before getting out of his car he calls 911 and telsl them he hit "a man in a fur coat" he then gets out of his car and looks around but cannot find the man, police arive and end up getting a canine unit out to search for the man. The canines pick up a scent trail and follow it for a long distamce (more than a mile I think) until they lose it into a swamp.

After-the-fact it was decided it was a BF and not "a guy in fur coat" because, no person could get hit that hard and walk away, much less 1 mile. Even if they did walk away why would a person go into a swamp. The subject was not lying about hitting something because in the police report they did report damage to his car and the dogs did pick up a definate trail. Oh and if it was summer why would you wear a fur coat in summer?
