Here's a couple of easy fixes that might help. I realize that some are push trucks but still block the view. They put those stands there too which no one sits down in them. It totally blocks the view from the grand stand. (your paying customer) A couple of these vehichles didn't move all night.
These vehichles are essential during the night but not during the feature. But they block the view in turn two. Figure it out. You need to move them. Totally blocks the view from the stands. So going into 2 blocked, entering 3, all the way through 4 blocked by personal vehichles and trailers, then blinded by trailer spot lights left on during dark hours. These are easy fixes. Maybe only park open trailers in turns 3 and 4.
