Family enclosure, a 1st team game, ideally against a weaker team with a big away following. Go early, wander round the ground, go to the gift shop (sorry!), have a pie. Get seats as close to the pitch as you can, pay more if you need to. St James’s is an awesome place for a first game as it’s always packed and the atmosphere in my experience is awesome.
I went to my first proper game (been watching my dad play non-league since i was born) at a similar age, Villa – West Ham, stood in the Holt End. I remember very little of the game but the smells, the noise, the excitement stay with me, it was magnificent. I don’t really follow football anymore but the excitement of that match still occasionally drags me to games.
