I have absolutely no idea what the first part of your response is talking about ??? so i'll make my point using an example. What is the harm if a track like maple grove wanted to hold an ihra race in april. your telling me an ihra race in April, can effect the bottom line of the nhra event held in late September ? I believe NFL stadiums and NBA basketball arena's hold college football & basketball games also. and you can argue college football/basketball competes with the NFL/NBA for an audience. without really checking I bet nascar and indycar tracks, hold non nascar/indy sanction, car racing also
Quick history lesson, IHRA was originally formed as a direct competitor to NHRA by a couple of guys (Larry Carrier was the principle) who were mad at Wally, and didn't like what NHRA was doing and thought they could do it better. That hatchet has never been buried. IHRA was competing for the same drivers and teams to leave us and race with them.
The NASCAR point I was making is that no one calls Hendrick or Gibbs and says "Instead of racing at Daytona this week, why don't you come race at my event at Reinhart Raceway?" If I did that, ISC and NASCAR would certainly NEVER let me hold an event on one of their tracks. And IHRA did that in the early days. They did that as recently as two years ago.
The other point was that NHRA welcomes other racing sanctions as I mentioned, ADRL, NMCA, NMRA, NDHRA, and on and on, even this new organization is racing on NHRA sanctioned tracks. But IHRA has their own member track network and still competes DIRECTLY head to head with NHRA for those member tracks.
Just for the record because the internet doesn't allow for inflection or facial expression, I'm discussing not arguing, just having a friendly conversation.
