Thanks for posting that clip of Chris and his banjo, Wayne ! It's been a while since I've heard Groundhog-- (key of Bb. for you musicians), and Chris does as fine of a job playin' the old time banjo style as I have had the the pleasure of hearing!!
Sometimes we call them "whistle-pigs" around here, and come spring, the greedy little fellows will eat anything green, especially in the garden.. They are not too bad tasting, either, though I like venison backstrap better..
