I have one small confession to make.
I only learned about Woodstock a few days before the event. It sounded like a great time, and as it happened I needed to drive nearby on Sunday, the last (scheduled) day of the festival. I had been visiting my parents in Brooklyn and needed to get back to work in Syracuse.
It was raining that day, which dampened (no pun intended) my spirits a bit, but I really wanted to see what was going on. I drove as close as I could, got to roughly the vicinity in mid-afternoon, parked the car on the side of the road, and started hiking in. By the time I got to the fringes, I could see that it was more or less complete chaos, and decided it wasn't worth it to keep going.
I hiked back to the car and went on my way. So I suppose I could claim to have technically been "at" Woodstock, but not really.
Great memories.
