One game we had close encounters was Wales v England at Wrexham , Wales won 4-1 I think it was around about 79/80.
My mate had just bought an old Morris Minor post office van and because it was red he decided to hand paint it with blue gloss Cardiff City coluors.
Anyway he said lets go to Wrexham to watch Wales v England ok so 5 of us crammed into the van and off we went. Got to Wrexham straight on the piss then went to the ground on the home end early only to find it was occupied by loads of English . I can remember a crowd from Doncaster/Chesterfield/Leeds/Sheffield/Grimsby and Cockneys all together battling with Wales fans who were mostly Cardiff and a few North Walians probably Wrexham this continued throughout the game.
After the game we were obviously jubilant and on the journey home disaster struck the van ran out of fuel between Wrexham and Hereford I can't quite remember where it might have been Leominster area don't really know it was middle of nowhere country.
So we had to find a garage to do this we would require a lift so we started to wave our Welsh Dragon flag to vehicles coming towards us in the hope they would stop and assist.
After half an hour or so of doing this a white transit van with red and white scarves hanging out came to a screeching halt about 50yrds up the road from us.
So we gleefully started running towards it thinking at last these are our saviors when suddenly the back doors burst open and out piled what I can only describe as a pack of gorillas with full beards swinging chains & bats throwing empty beer flagons at us screaming " You got the wrong ones this time you Welsh kents"
Now we were no match for these fully grown cavemen as were at the ages of 17 to19 so we legged it knowing they could'nt catch us but they surrounded my mates van smashing the lights /mirrors and windscreen then drove off.
To this day I don't know who they supported but it definitely was'nt Wales .
