I wasn’t there this morning myself, but I was there on Saturday afternoon and I have to say based on how the pitch was then I was very surprised to hear it was called off.
The pitch was soft in places but it wasn’t holding any water and wasn’t mucky or anything like that on Sat afternoon.
There was rain on Saturday night/Sunday morning but not sure how bad it was.
But based on the condition on Saturday I can tell you that I’ve often played and been at matches on much worse pitches both in Wanderers and away matches.
As an aside, @AlwaysNumber1, you must be paying a long time if this is the 3rd or 4th time you have had games called off in Wanderers, I can only think of 3 or 4 matches called off on the morning of the match for years, and one was after a downpour of snow the previous night and as far as I remember the opposition didn’t travel that time as there was no way anything was going to be played.
I can’t be sure, but I would think it’s quite unlikely that all the others called off were all against Whitehall!
