Maybe it's a local thing... We called them saddle blankets, but horse blanket is the same thing.

I sure wish you would send me that OLD note so I could put it in my trader box and I would send you a FRESH CRISP NEW ONE!

Everyone reading this the $5 note Andy is displaying and the $1000 I displayed are close to the same value..... THAT should tell you someting!! Collect old $5's not $1000's hahahaha
