Born and raised in Point Pleasant, WV. Mothman stories weren't any big deal when I lived there (up until 1992). In fact, I don't think anyone my age actually knew the stories. I never did - I just knew the name and only bits and pieces. I asked my brother and he told me what was basically talked about earlier in this thread.
However, some claim that the Mothman still exists and resides in the TNT area. FYI, TNT is just a swampy wild area with a bunch of fishing holes and dirt roads. Pretty dangerous area at various times of the year. Police have unspoken rule to not go up there unless absolutely necessary.
Anyway, my Mom's former Insurance agent was the County Sheriff during the Mothman sightings and he claimed that he was in the TNT area and lost the use of his radio (some sort of electrical disturbance) and "felt" the Mothman there. He was always a nice guy and pretty stable, but you never know. :Q
