It was a sad day when they closed RMR (Rocky Mountain Raceway) here in Utah a few years back.
Yes, it came down to the almighty dollar.
We have another racetrack at Utah Motorsports Campus (primarily a road course, no dragstrip) that had some legal real estate issues with some shitty Chinese company until the chinese backed out thankfully. https://www.hemmings.com/stories/2017/12/13/utahs-rocky-mountain-raceways-to-close-after-2018-season
