I have a long and checked history on this topic. My father grew up in Flushing in the 1950's, as a Yankee fan, because they were good, and Queens did not have a team, and he had a uncle just 15 years his senior, my great Uncle Boomie, that used to take him to the Bronx for baseball. He maintained his Yankee allegiance through the 1960's, though, after Shea opened, he probably attended far more Mets games than Yankee games due to convenience (my grandparents lived on 141st and 70th Ave, just 15 blocks or so from the stadium). My folks moved upstate after getting married, though my grandparents remained in Queens. I was born in 1973. As a kid, living in the Hudson Valley, we were far outnumbered locally in our neighborhood by Yankee fans, much as my kids are now. And the MFY's were the big deal, due to Reggie and Billy and the "Bronx Zoo." There wasn't all that much cause, as a kid where I lived, to be a Mets fan. My father, ultimately, turned on the MFY's when Steinbrenner bought the team. He was not a fan. As the 1970's progressed, and the part of the Bronx where they played got worse (in his estimation), he switched his allegiance to the Mets. It didn't hurt that my grandparents continued to live in the neighborhood. We made dual purpose visits to Flushing -- dinner with my grandparents and then a game, or, a matinee followed by dinner. As a very young child those trips included my brother and mom, neither of whom was or is a baseball fan, but ultimately, those games were just trips for Fdad and I. My grandparents are not alive any more to visit, but Fboy and I continue the family tradition that Fdad and I started all those years ago.
