I've attended several back in the day, and watched every one since they've been televised / streamed.
Honestly, that A-Main was below average for the event. They spent a lot of time reworking the track, but they missed it and the groove was too narrow. A lot of great racing throughout the week, and the B features were the best racing of Saturday.
I don't rate races, but that's my opinion. NASCAR Bristol is a totally different animal because they are going to aim for an extremely hard packed surface to withstand 500 laps. It will inevitably take rubber (which is what they're trying to avoid at Chili Bowl), and more resemble pavement.
