Lots of good memories of the Polo Grounds. I got to see one of Duke Snider's last homers in New York as a Met, as well as Sandy Koufax pitching in his prime at the PG.
Actually, the last year or two of the Giants at the Polo Grounds were kind of sad with total attendance under 5000 at most games. But, it was great for snagging baseballs in the almost empty stands.
