This is really cool. My first game would've been around the same era (although I don't recall exactly when, maybe a year or two earlier) and with my dad as well - maybe we're around the same age.
I have so many fond memories of Kiel Auditorium - it was such a unique venue and a cool place to see a game. I wish it could've been preserved somehow. I'm pretty sure we always sat in the upper deck, so I definitely remember those ramps.
