I grew up in Dover and I have seen the Demon. I can't say what it was but I can only tell you that it was nothing I have ever seen before. I was driving home from a friend's house in Holliston at about 11:00 PM after hanging out, talking about school and the girls we wanted to hook up with. There were no drugs or alcohol in my system. As I turned onto Woodland Rd. off of Rte. 16 I was shocked and startled by 3 black crows that flew right in front of my windshield, pretty odd for 11:00. I composed myself and continued driving. I took back roads to Bridge St. in Sherborn to get to Farm St. in Dover. After I went around the hairpin turn (anyone from the area knows the turn) and began to go over the bridge to cross the Charles River I noticed a dark shadowy object move swiftly from the woods to the center of the road where it stopped. It turned its large round head towards me slowly and glared at me with giant round eyes about the size of tennis balls. It stood on 4 legs and was completely hairless. It had no tail either and was the size of a huge dog i.e. Great Dane but much stockier. It had triangle shaped ears and a snickered snout that reminded me of some drawings I have seen in history books on the devil. I came to a stop and starred it down for a good 5 seconds before it slowly turned its head and swiftly disappeared into the woods to my right. I have no idea what it was but I do know it was not a dog or coyote or anything I have ever seen before.
