Clues. So many clues!
I’m at home, enjoying the evening, but just had to post this from my counterpart:
“Just had a girl in here who was on her way home from a picnic in Rockford, Ill. She lives on the north side of Chicago. Didn’t the Welcome to Wisconsin sign give her a clue she was going the wrong way?”
Apparently no more than going past several noteworthy Wisconsin towns, the entire city of Madison, a few prominently advertised cheese shops, a couple thousand cars with WI license plates on them, and the Wisconsin River. *sigh*
