Great pictures, Lou!
I recently watched the movie '1' about Formula 1 largely from the angle of safety. If you haven't seen it, I advise it.
Some old pictures have people standing a few yards from the track. Some viewing locations were on the top of a bluff that was carved out to pave the track. The views must have been amazing but the tracks were incredibly dangerous. At the time, I thought the safety issue was silly. They knew what they were in for and if it was too dangerous, they needed to slow down. That sounds reasonable but it really isn't given the reality of who was racing and why. I still miss the tracks that weave through the woods like Nurburging, but I'm really happy that deaths are unheard of now.
