p.s. My CT. zip code shows 50% NY Yankees and 28% Red Sox, but that's because 50% of our housing supply is owned by weekenders from New York City. The Red Sox are in the majority from late afternoon Monday to early evening on Friday.
Jim,
I find those graphics fascinating. Being originally from CT myself, I always considered the Connecticut River, running north/south down the center of the state, as the line of demarcation between Boston and NY fans in all things sports - baseball, basketball, football, etc. From your link, the River is indeed the line for most of the state. I also find it curious that the Mets in fifty years have not gained a foothold in the Nutmeg State.
That said, and to bring the thread back to something golf related, one can't be too careful. A couple of years ago I went to pay a visit to the GCS John Robideaux at Winged Foot. Naively assuming that I was heading into the heart of Yankee territory, I proudly donned my navy blue NY baseball cap, only to arrive at John's office and see, much to my dismay, not only a Red Sox pennant but a poster that declared flatly, "Yankees Suck!".
John was most gracious. After informing me I was wearing an ugly hat, he presented me with a Winged Foot logo cap, and otherwise treated me cordially.
