When my daughter was a student at what is considered the best public high school in Oakland, CA, just a couple of years ago, she brought a water bottle to school with her every day rather than use the drinking fountain. The reason? Several years earlier, two students had been caught having sex in a bathroom. Therefore all bathrooms were locked except for one for each sex--for a student body of about 2,000. So the boys took to peeing in the drinking fountains. A parent uproar finally got the bathrooms unlocked.
