[AT] Denim Barn Frocks

[Bob McNitt]

That's the one I was referring to. "Frock" and "Coat" meant basically the 
same thing in many rural areas when it came to a light work coat to keep 
inside clothes clean.

Must be a local thing as I've never heard the term used around here. My
Grandpa used to have his barn coat hanging behind the door when he went to
feed the cows etc... It was blue denim and had big deep pockets and hung
down below his waist. A duster I always thought was about to the ground.
