I've been to Anfield many times and simply turned in to a side street and parked. Walked back up the street and noticed I'd parked on Ince Avenue!! Had no choice but to move the car in case my parking on a road named after a United player might be unlucky.
Well once, when I was younger and more 'competitive' against Man Ure fans and we were playing them at our place, we noticed several first-timers to the area make the classic mistake of parking on that big triangle opposite the Cabbage. One of them took his Man Ure sticker out of his windscreen so alerting us to where his loyalties lay. As ever, the deformed mutants were kept in for half an hour after the game as they obviously can't be allowed to mix with polite society. On our return, we noticed our Manchester chap had received an unfortunate parking ticket. Showing admirable comradeship, I prevented him from receiving the bad news on his return to his vehicle and removed it off his windscreen for him. Wasn't that commendable of me?
