Racetrack developers missed the whole small charming stadia thing that was happening in baseball and starting in the 90s built a bunch of cookie-cutter 1.5 mile ovals in **** cities all over with capacities of 90,000 or so. Many of them don't host Nascar at all anymore; almost all of them have drastically reduced capacity. Daytona at one time sat 170,000 and now max out at 100,000. Dover Downs went from 130,000 to 54,000 -- it was all grandstand so they just took big chunks out.
