Share 'Flying Squirrels'

I understand that the Northern Flying Squirrel is native to North Carolina, but I wonder if anyone knows the extent of that animal's range in the state. I've never seen one (I live in Monroe), but I did have something 'fly' laterally past my head one night and land on a tree a few feet away in the woods behind my house. There was a little moon and starlight, but not enough to see what it was at...
