The split years ago forced the France's ISC to buy the Penske tracks because Bruton Smith owned more tracks than ISC. Gave all the power back to ISC. Bruton was the only person who could have split and maybe survived.
A strike by the charter owners could really put a final nail in the coffin. Look how the IRL/Champ Car struggled, if it was not for the INDY 500, not sure that would have survived.
Nice thing now is how a Saturday night NASCAR race barely effects a short track Saturday night. For a few years it looked like short tracks would have to shut down on a Bristol or Richmond Saturday night.
