Ah Ha, this will probably go better here than where i originally posted in the PRI thread. I am glad others thought it was interesting enough to chime in about. I not sure if it is all accurate, but below is what i remember hearing,

(MOVED)
it was a side note a few pages back, but the Astro Dome was run in '69 and '70. Dad told me quite a few stories about those races, but i am not 100% on the winners. Duke said Gary Bettehausen which sounds right for '69 to me. it seems like '70 was a dual feature deal with Lee Kunzman winning one and Foyt the other. Where is Bitterwind at when we need him, i am sure he knows the answer.

there were a quite a few good stories my dad told me about these races that come to mind, but regarding the winner. My Grandfather and Tattersall actually protested the finish when Foyt won. it was pretty slick and about halfway thru the feature the fast way around was cutting down into the infield thru the corners. By the end of the race most of the feild of cars were running almost the entire lap inside of infeild even down the straightaways. Dad was standing in the infield watching and signaling Tat. I remember him telling me by the end he was standing in the center of the infield next to Andy Granatelli, who i think was the promoter, backed up against the trophy and the cars were so far in the infeild he he felt like they were racing around his feet. Tat never left "the original" racing surface to cut thru the infeild and ran fourth or fifth. Grandpa and Tat protested telling USAC that they should get the win since they were the highest finishing car not to race in the infield. It didn't get far, LOL. But in 1970 i expect it would be a pretty bad deal to take a win away from AJ in the heart of Texas.
