13. The Trash Piled Up

Not surprisingly, the debris of 500,000 people on a three-day camping trip was considerable. It took two weeks to clean up the mess, and because of the concert’s financial difficulties, the cleaning crew was not paid promptly.
14. Drug-related Death Count

It is estimated that nine out of ten Woodstock concert goers smoked marijuana there, but only 33 were arrested on drug charges. Some brown acid was in circulation during the concert, and many a bad trip was reported. Aside from one fatal overdose, the festival was relatively without incident on the drug front. However, a handful of artists who played at Woodstock 69 ultimately met their demise at the hands of drugs. This list includes Janis Joplin, Jimmy Hendrix, Keith Moon, Tim Hardin, Gary Thain and Alan Wilson.
