I'm going to commit an act of heresy for someone who grew up in the Gallipolis, Ohio - Point Pleasant, W.Va. area. I am old enough to remember the Mothman, and I really don't care to hear or read much about it anymore.
The Mothman could have been one or more of several things. In some sightings, it could have been a prankster in a suit. I've even heard a name used.
A lot of folks note that the Mothman's last sighting was before the Silver Bridge fell into the Ohio River on Dec. 15, 1967. It could be that the person who dressed up as the Mothman was on the bridge. Or he had a family member or a friend who died when the bridge went down.
Call me a curmudgeon, but count me as one person not fascinated by or really that interested in the Mothman legend.
