the comment on the cage vs. no cage brought up another memory. In 69' cages were optional, and they were also going to run wings some that season. the Astro Dome was the first race of the year. Grandpa showed up with the cage and wing on top along with a signed letter from Bob Stroud, no relation, from USAC saying that the wing was legal for that race. Kenyon was the only other car there that had a wing so USAC decided to go without the wing ofr that race.
