Have seen white squirels in Flora IL. and also in Kenton TN. Did not get close to the one in Flora Il. to determine if it was white or albino. The ones that I have seen in Kenton TN are all white and are not albino.
I've seen the black Michigan squirrels. My wife is from jackson, mi. I was all "what the hell was that" the first time I saw one! I saw a white one a few weeks ago between Wilbur and Monrovia, he did have the fox red tail though. I've seen a couple around here when I was a kid, but now we are getting a lot of gray squirrels.
