I have seen them up close, too. Trapped 11 in my attic one winter...catch and release to the nearby State Park. I saw one once in the evening after I had been doing treework for a friend. Jim and I were outside in the yard and his wife stepped out on the sideyard porch. She had a Marge Simpson hairdo, piled up hair high on her head. Jim and I watched a flying squirrel launch from that oak and land on top of her head...hilarious watching her tap dance and flail while that squirrel tried to re-launch...they like to run up high to take off again. It scrambling on her piled up hair was awesome.
