Good question :). Good pic of him though.
I'm guessing he was up to no good :) Squirrels are really funny to watch!
Love those little critters. I'm always leaving nuts and such on our deck for them. :)
He was wondering if there were any nuts up there to come and store in the engine of my car... oh wait... that's not my yard. Sorry, it's all I can think of when I see squirrels or chipmunks (one of which has taken over residence of my car on more than one occasion). ;)
