We played at Carlisle two years running. A 2-0 win and the 0-0 you mention. I get them mixed up but at one of them there was a rumour went round that some City had travelled up on the Friday night and a local had been stabbed. It was probably bullshit but it resulted in every nutter in the area out at the crack of dawn on the Saturday morning, looking for any City for revenge. Was a lively day. Have no recollection of how many were there either time though. I can’t even picture the ground now, even though I went both times.
