Yes. It says WITS END.
Wit's End is not a phrase I employed a whole lot, in a former life. It was only on my radar about as often as, oh, "plentitude" and "moisture." But it comes to mind more and more frequently these days. Like when the Spouse brought home a Bear in the Big Blue House potty DVD for Thing 2 to watch. You know, to encourage him. And Thing 2 is enthralled! captivated! enamored! peeing on the carpet! while the encouraging Bear sings about "It's time to get to know your potty ch-airrrrr...." !!!
Maybe there's a reason that Wits End intersects with Mexico Road....
