In the days of terraces and turn up on the day with your thruppence ha'penny it wasn't uncommon. I even knew a guy who used to do this as late as the 1980's. A guy I knew from East Anglia would go to both Ipswich and Narch, presumably deck his tractor out in different colours every weekend. On the South Coast you'd find peeps going to Saints and Pompey. Presume you'd go to the home end for derbies.
Imagine ditto Liv-Everton, Sheff Weds-Utd.
As a young teenager a group of us went on rotation to spurs, woolwich, and West Ham this was in the late 80s. We avoided Chelsea though. Hardly anyone supported them back then.
We all supported different clubs - even had a coupe of Everton fans in the group - but it meant we could go as 6 or 7 + of us.
Pay on the day, get to the terraces for about2pm to find a spot… crazy to think about now when you roll in 1 minute before kick off.
