Great photos! I have squirrels in my backyard but I've never gotten any pics as good as yours yet.
I couldn't help thinking about my sister, though. She's six years older than me and has been terrified of squirrels since she was a little kid -- not sure why. But I always heard stories about her walking home from the schoolbus stop and freaking out on the squirrels in the park (we lived on a dead-end street with a huge undeveloped park across the street).
One day she was halfway home, saw a squirrel, and was absolutely convinced it was stalking her, ready to attack. She turned around and FLED! She ended up in the house where a couple of nurses lived; they gave her cookies and milk and phoned our mom, who had to drive the car over and rescue my sis.
I know, I know, it's not funny when a little kid is scared . . . but she's a grown woman now and she still shudders at the thought of those cute little squirrels.
