The first time I saw a black squirrel I was attending Kent State University. At that time (many moons ago) they were pretty much contained to that area of Ohio. Ten rare black squirrels had been imported from London, Ontario in February of 1961, but I don't know why. The Black Squirrel Festival began in 1981. Now I live about 30 minutes away from Kent but see black squirrels all the time in my neighborhood. Have you seen them around your neck of the woods?
