I did see the picture of the pitch in the middle of the prison when trying to match up Google Earth and some old maps (which put the Manor Ground immediately southwest of the prison, and, by inference, the Sportsman a tad southwest of that and nearer to the canal and
drainage ditches that, I assume, were the source of the flooding, but we are only talking a difference of field or two
at most; and if you have primary sources, I'll bow to those).
We have a daylight basement, and
at the first really heavy rain water came in through the brick wall - some leaves had piled up under a deck and blocked the usual
drainage ditch.
