I've got a closet full of Plaid shirts, blue jeans, and workboots. Unfortunatly doesn't go well down here south of the Mason/Dixon. Seen more as a red-neck thing than a blue-blood Yankee.
Remember, I grew up fairly close to L.L. Bean territory. Ever heard of them (you Canuck wannabe!

), they're on the good side of the St. Lawrence. Et toufe,' mon ami!

Oh, to stay on topic, flannel shirts are most always untucked IMO!
