well, thereby hangs a tale. When the Briggs rebuild was done, the CF corner was more square, the flagpole was in play, and it was 440 right into to the corner where the flag pole was. But after some years they put a fence across the CF corner so there was 25-30 feet or so of fence square to home plate and the flag pole was behind it - no longer in play. the ground crew used it as a storage area. The distance to that fence was ~425, but they never took the old 440 marker off the wall and eventually just kept repainting their little fib. After the ball park closed, Google earth got a shot of the field after they had torn down the interior fence, you still see the warning track end at the line of the removed fence. Measured with GE, it was indeed 440 to the original wall, but 425 to where the fence was.
And there is your Tiger Trivia for the day....
