Derby, i was going to say Reading but i nearly lost my car and spent over an hour running round reading trying to find where i parked! especially as the car park closed 30 mins after the game!
The worst has to be Palace, went with a palace fan too which made it twice as bad Sheff Utd on that cold night in october wasnt much better either - though 1 think that sticks in my mind from that game was a guy behind me said "we may only have 4 fans here but least we are making some noise!" lol
