I also do not dispute any facts stated by Waldo above however he writes from the IMS/IRL/Indy viewpoint. During that time frame the USAC sanctioned only one race, Indy. CART santioned all the others. CART owned all the cars and the teams except for a few Indy based small operations known for running at Indy only. CART was becoming quite successful and was under pressure to start new venues in US and Canada. Phoenix could be replaced with a new venue. Keep in perspective that we are talking about seasons with 20+ races per season with high car counts.
Granted greed got the best of decision makers on both sides. Feelings, egos or saving face became factors in those decisions. Mistakes, poor judgement and poor management played a role as well. Protecting one's turf and source of revenue was essential in both camps.
Finally, TG created another series. It took 12 years of split before KK gave up the fight. So there is one series now. TG with hind sight has admitted to some of his errors in judgement. I am sure that Roger, Chip, Pat, Gerald and Carl could all admit to their share of errors and/or greed led decisions.
It is time to move on. No amount of verbal bantering with each other will accomplish a thing other than perpetuate hatred.
Again, give it a rest and remember why we have this holiday off to go racing.
