A few years ago going through Marionville, Missouri we saw lots of white squirrels. I see online there are other places like that.
Here in Virginia we have Grey, some Red, rarely a flying squirrel but down in our woods these (I call Arnold Schwarzenegger) squirrels...I think they're fox squirrels, real muscular.

To reiterate, we have resident gray squirrels here that are white. I believe they have pink eyes. Seems we have three in our neighborhood that visit our feeders. Here is some pics I got this morning of one.
