City squirrels are smarter. In Baltimore they'd use the aerial phone lines as highways. They'd tightrope safely up to my 2nd story balcony when they saw me for their daily spoonful of peanut butter.
Hey I live in the city, well, I live in Tulsa, Oklahoma. The squirrels here are pretty smart, we just have a lot of back roads, streets, and expressways, and highways. And a lot of cars.
