I watched this squirrel run across the street to the softball concession stand - and disappear. While hunting where he went I turned around and he was peeking out the hole he'd made in the roof. Nicely lined in there with grass and twigs (I checked when he left). Not good for things like electrical wiring I'm afraid. Mentioned it to our Parks Manager - His home will be sealed off tomorrow (Did remind them to be sure he was out first:) )
