I don't know when the inside wall was installed on the backstretch. My first time at that track was in 1968 and I was always in the stands and I couldn't see that far away. That 1966 race that you were at must have been the opener and maybe some of the inside wall and other things weren't built yet, because they tried to get an event in before the end of the year. I just don't know. Kind of just like what happened there in 1982 when they opened in December. Maybe that inside wall was added the next year after Whip Mulligan crashed down into the tunnel on opening day in '66.
