Hour and a half....i once had a car that was slow like that....best advice do what i did get rid... .lol...
I parked in there, often do. Never seen it as busy as it was, four and five deep on the field and folk parked all through the gate into the next bit too. Got home by just after six. That said I live in donny and picked my online big shop up from Asda in carcroft on the way past.
