There Weren’t Enough Toilets
Organizers had no idea that so many people would show up for the Woodstock festival, and as a result, they didn’t have anywhere near enough toilets. They only had about six hundred toilets, which is roughly one toilet for every seven hundred people.
It got so crowded that people couldn’t get out to go to the bathroom, and some people just started going to the bathroom right where they were standing. There were roughly half of a million people there, so if you managed to get out to go to the bathroom, you would never get back in.
