Twink - I have been there many a time. Glad you made it in time.

This is the reason I carry a empty coffee container in my car (as well as a sheet to create a makeshift bathroom). DDs think I'm nuts but they understand as we have had to make many urgent stops running around town. I know where most public restrooms are and which ones are the cleanest. LOL AND, when traveling long distances that coffee container is a must!
