I'm sure most of us appreciate finding a clean public bathroom when we're on the road. Here's a website, mizpee.com, I recently discovered that helps you locate one via your cell phone. Just enter your street address and it is suppose to point you towards the closes stalls.
The listed bathrooms are rated by rolls of toilet paper. 5 rolls signify a clean bathroom and 1, well, do you really want to use one with a 1 rating?
Currently, the website only locates bathrooms in major U.S. cities, so if you live outside these areas, you'll have to hold your bladder and continue to do the dance.
