My earliest memory is being at a Mets Cubs game in maybe 1976-1977 sometime, that went an interminable amount of innings. And that I wanted to stay, but my mom and brother were all done, and we left in the 13th or 14th inning (OE: I looked at baseball-reference but could not find a Mets/Cubs extra inning game in those years, it may have been a different opponent). I remember we always used to get the single serve vanilla/chocolate ice cream cups at the game, and that that was a big deal. I remember also always bringing my mitt, even though you'd need a NASA booster to hit a foul ball up into the rows we normally sat in.
