When I used to ref in the Tyneside Sunday League there were a few teams over that way and i was pleasantly surprised how many Safc fans were there.
As an aside, I was in the 02 Westgate Road last night and "toon toon black and white army" pretty consistent during the show...sigh.
And Whickham. In my experience Safc fans over here tend to be diehards as in I dont really know non match going Safc fans here.
