We imagine that choosing where to camp wasn't the easiest process. Half your mind is already busy trying to remember where you abandoned your car, you're surrounded by way more people than you were expected, and the site is filling up fast. You just want to get your tent set up and explore your temporary surroundings, so you're likely to just set things down in the first clear space you can find. And then you have to find it several hours later, in the dark. Possibly whilst high.
The path names laid out by the organizers didn't really help matters. Imagine the conversation. 'Do you remember where we put the tent, man?' 'I don't know, dude, I think it was on High Way. Just off Gentle Path'. 'High Way? Are you sure it wasn't Groovy Way?' 'I dunno man, it could have been Groovy Way, too. I dunno. I'm high'. Perhaps choosing street names that weren't part of everyday hippie conversation might have been a better idea.
