I have even been to Oxford to support an away team.
Me too. Went once with a Rotherham-supporting mate. Wore my Swindon scarf to that one, and narrowly avoided getting my head kicked in. Would have served me right, frankly, if I had.
And went again with a Pompey-supporting friend. Evening game that time. Bizarrely, Portsmouth were 5-3 up until 2 mins from the end, and managed to finish it 5-5.
