My most memorable regular season moment was my 1st game.
I'm 10 years old, my first game EVER in a MLB park(at the Stick) and we're doing pretty well('78 Season) and I get to see Willie Mack play. I sat along the 1st base path 2 boxes up between Home and 1st. My Uncle took me to the game and let me ruin dinner with so many Carnation Malteds it wasn't even funny to my Mum later.
I never once left my seat and we stayed through all 9 innings. We lost 2-1 to the Cards because Brock took 2 bags off us(I think it was two anyway) and it was a hard fought loss. What made things memorable for me was I was looking forward to getting Jack Clark's autograph but he didn't play that day.
I had pretty recently moved to the area and hadn't had any sworn allegiances(though my stepdad was a confirmed Reds fan) and just taking in a Loss and how our guys handled themselves changed that forever. All because my Uncle(who is now retired) was given 2 tickets as an off duty Officer and decided to see if his nephew would like to go. Boy howdy! I jumped all over that and I'm glad I did. It's been a rough, but fun go and I wouldn't change it for all the money in the world.
