Dad was a ST-holder from the 70s so had no choice really! First item of clothing I ever received was a tiny replica shirt from the 1989-90s season.
Used to get to as many games as I could as a kid, but that was obviously tough as wasn't old enough to go on my own and Dad was in North Stand Tier 2, which is predominantly ST-holders. Used to get to about 6/7 games a season though, usually Champions League or midweek cup games, since this was when some of the regulars would have spare tickets. Also used to get to the odd away game with my Dad. Earliest memories are a draw with Wimbledon at OT, beating Leicester at Filbert Street, beating LSK Lodz 2-0 at OT, beating Forest 8-1 at the City Ground and drawing 1-1 with Newcastle at St. James' Park.
My Dad always said he would hand his ST over to me when I turned 16 and I could travel to games on my own. At this time, we were living in Nottingham, so I used to get the supporters bus from outside Morrisons in Eastwood. For anybody who has read "If The Kids Are United", Dad & I were born in the same mining town as Tony Hill (Jacksdale). Bit of a stretch to say they were mates, but Dad knew Tony and gets a brief mention in the book (or so he said, in the latest version) Went to practically every home game from then until about 2010/11, so a good 5/6 year run of barely missing a game. By this time, I was living in Hull, had no money and couldn't afford to renew (and the travel).
I moved to Manchester in 2012, got two STs together with Dad in about 2015 (it was LVGs first season, whenever that was), held those together until 2018/19. By this point, Dad was really ill and couldn't travel. I used to go with a couple of mates but we all sat in different parts of the ground. The atmosphere around the club was horrific, even though we had just finished 2nd the place was toxic. Sort of fell a little out of love with the Match Day experience. Queuing for an hour to get in the pub, £40-odd a ticket to sit in silence (apart from the booing/whingeing) on my own with an empty seat next to me....£5 for a pint, £5 for a crap hotdog, £6 for three stops on the tram...just didn't seem worth it.
Still follow Utd as closely as ever, but from home/the pub now. Go to the odd game when I get a free ticket or something corporate. Do think the game as lost touched with the supporters to a large extent.
