When Was The Last Time You Used A Porta Potty [PHOTOS]

Although I'm not much of a Porta-Potty fan, when you gotta go, you gotta go. I used one several times recently and was impressed with how nice it was. It smelled decent, was stocked with toilet paper and was relatively clean.  There was even a mat on the floor like in most people's bathrooms.
