I think most fans of a baseball team have positive experiences at their hometown stadium (if they’ve been lucky enough to attend a game in person). We’re usually just so happy to be present in the hallowed halls of our chosen team and see where those games happen in real life, that everything feels delightful and happy. It’s easy to have a good time when you’re on your home turf.
But sometimes you go to a game at another team’s stadium, or have an encounter in some other way with the fans or players of another team, that leave us feeling warm and happy and welcomed.
