"everybody go home. we're too greedy to pay overtime... and too cheap to have enough workers vetted and on the payroll, ready-to-work if and when needed."

Closing the stands under those circumstances is understandable, albeit reflects poorly on the organization and planning.

Refusing to issue a refund afterwards is completely unreasonable.

They didn't plan on the ground force from the cars sucking up the water valve covers in the street of the race track which requires asphalt repairs so I don't think we can expect them to plan on delays for staffing either. I have to think they were already maxed here as it was.

I'm surprised to read they are running cars at 230 am to 4am. I understand the time constraints but that racket at the middle of the night. Good thing it's in Vegas I guess.

As for why they water pipes under roads a part of me doesn't get for disruptions to traffic. I would have thought these would be better run under sidewalks and the edges of roads but I'm a layman in these areas. I suspect there's good reasons for this?
