I think a nascar track would do well in Pittsburgh. weatherwise, maybe not. you got a demographic east and west and south actually.. 100 miles in any direction not north gets you that "rural" crowd that enjoys racing.Pittsburgh sports marketing studies showed limited interest in an NBA team and a race track for both Indy & NASCAR races.
Football, baseball, and hockey town!
The spelling of NASCAR confuses and scares the locals!
I live 300 miles away in an area of PA where racing is very popular.
