I was looking up old facts and such as I seem to do when I am bored, and came across this page talking about the classic Polo Grounds. Home to the Giants, Yankees and Mets from 1883 - 1890, the cathedrial of a stadium hosted some of the best players ever to step in between the lines.
Anywhere from 270 ft to 505 ft and with walls of concrete, the Polo Grounds are a true part of baseball history.
