THE WHITE FURRY CRITTER that showed up in my backyard in Surrey, BC, the other day was totally unexpected. Squirrels of beige, black, brown and gray have scampered swishing their tails along the climbing ivy. But this is my first sighting of the white variety. Apparently, they are more common in eastern Canada. As the video link shows, white squirrels even inspired a song and have become a mascot and claim to fame for Exeter, a small community in southwestern Ontario.
