My father had his kids sitting in end zone seats at Rice Stadium before the Oilers moved to the Astrodome. Watched Joe Namath get humiliated in his AFL debut in 1965. (note: I never watched a game in Jeppesen Stadium and never watched the Colt .45s in Colt Stadium). I remember the stench of cigar and cigarette smoke under the stands at Rice Stadium. I was a kid and I was watching live sports so it was all good.
This was the year that made me a football fan - watch how often defense and special teams made up for a relatively weak offense that had to trade for a starting QB after the first four weeks:

I was at all the home games.
