When a visiting friend asked if I wanted to go on a run in Philadelphia, I did a lot of planning. Not just our route, but where to go to the bathroom. It did not go well.
I took the rapid-transit PATCO Speedline, which doesn’t have bathrooms on trains. The station I left from in Southern New Jersey didn’t have one either, nor did the one where I arrived in Philadelphia. When I arrived at my friend’s hotel, the lobby’s bathrooms were locked.
Fortunately, I was able to follow a woman with a passcode into the bathroom. But that was a matter of luck. Relying on whims of fate was my only option because the United States — and much of the world — has a public bathroom problem.
