Thanks for posting those Jack- it's really a cool perspective comparing the 2 time frames. Looking at it, I'm having a brain phart. I remember getting a pit pass in 1966 when it first opened up and going on the back stretch to watch the cars blast past us going about 140 mph. We were probably about 30 to 50 feet away from the track and I don't remember an inside fence or anything blocking us from standing next to the track. Was there an inside fence then? Since I'm a rather old adult now, I have been punishing myself for 51 years of how stupid I was.
