Well, in Columbia County, New York, they all seem to come to the feeders on my deck, winter & summer alike. We used to try to discourage them. Then, we started feeding them peanuts in the shell. Now, for goodness' sake, we've actually supplied a feeder just for them--a "Squirrel Lunch Box"! Here's a link to my squirrel set
