Well from where I stand, Waco is in the West - well maybe the Southwest, not the South.
And Ricky, ZP wouldn't know Polecat mainly because she's a city girl. If I'm not mistaken, the true polecat (or European Polecat) is a European critter (therefore more in her neck of the woods, assuming she went into the woods), somewhat equivalent to the American skunk in smell but looks different. We just naturally used the word to describe the skunk because of the similar smell. There are other variants of polecats throughout the "old country", i.e. Europe, Asia, Africa. But don't take my word for it, I'm just a country boy and polecat was good enough for me growing up.
