The Woodstock Festival took place on a dairy farm in Bethel the 15th through 17th of August 1969. And while many attended the event many were also stuck in traffic and never made it there for trying... The queue on the highway stretched all the way to New York! So that means that many out there recall what they did at this time fifty years ago, and that this was: being stuck in a car!
The very word "Woodstock" still means something so clear to people, and so naturally to people who weren't even born at this time too. It needs no explanation. If you say "Woodstock" you're done talking. People got you.
The word conjures up the immortal sounds of Jimi Hendrix playing the Star Spangled Banner. A classic moment in American history and the history of music.
