I got him from this great resource:
http://www.scarysquirrel.org/It's totally worth checking out - I love it
And yes, I saw many squirrels on my recent Stateside sojourn - all in NYC. We spent ages in Central Park watching them, and when we got back we were mortified to discover that we have about 30 squirrel photos and 1 squirrel video
Obsessed much?
Alas, I am still yet to see a Chipmunk. Or a Marmot, for that matter. I live in hope
