I hear about many sightings and suspected bigfoot activity. Many of these folks just want to get some feedback about their experiences. They do not want to formally submit their reports. To submit a report seems to mean that the witness has come to some sort of grips with their own experience. They no longer can brush it off as being nothing or an over active imagination.
But the importance of a published report also is that other readers are able to compare notes and perhaps be persuaded to post their own sighting. Especially important is a report from a new county. New county reports often bring other reports from the same area.
