Yes, I am, way back. I started going to Mets games with my Grandpa when I was maybe 4 or 5. I grew up at Shea Stadium. Mets>Cubs>Any National League Team (except the Braves)> Mariners & Twins> Meh. I tried to hard as a kid to be good at playing softball or baseball, and I was the suck. But my husband and I bonded over baseball when we first met, even though he,like my Mom, was a Yankees fan.
And I would root for, well, pretty much anyone before I would root for the Yankees.
