There was an earlier thread on this and I had listed these sites: www.bfro.net and www.bigfootforums.com The Fort Lewis incident is a classic. Both sites have audio files and sighting lists for states, counties, etc.

My 2 cents........sure there are hoaxes, but with hundreds of years of sightings over several continents and countries, thousands of varying sized casts of footprints, audio files, and countless reported sightings by all kinds of people(just think how many people have seen something and didn't report it).........it just takes one real event for this thing to exist.
