Thank you very much. To be straitforward, I didn't want to purchase the tickets and drive the distance to find out it doesn't have anything to do with HTA events.
I just have to ask someone who has been to these modern day events: how free are you to roam so you can take pictures of the race? Is it possible to get shots like the pictures in "vintage" threads, or is there some kind of strict access restriction for "normal" people?
It seems like back in the day, you could go just about wherever you wanted at whatever risk you were willing to take. I have a funny feeling the attitude is not quite as passive as that anymore.
