Stadiums like this use their parking lot for commuters during the week and for the games on the weekends. I live here, the hockey arena, baseball stadium, and football stadium all share lots/garages that are always full during the week too
We also have shit public transit so almost everyone is driving cars downtown from the burbs
Wait that's it? Up in Canada our hockey stadiums get used for minor league teams, lacrosse, concerts, and all kinds is variety events. You ONLY play hand egg in them?
I get community from my local sportsball fan club. We get together, sing, gripe/gloat about how we're doing, and watch each other's lives develop as we hang out at the tailgates year after year.
The other season ticket holders and I recognize each other by this point even if we haven't talked; wearing a team hat in public can start a conversation.
It may not be a type of community you care to participate in, but it is one.
This. Here in Europe they usually have transit stops and (very) little parking (by American standards). In Bucharest they close down the whole Road anyway when there's a match.
