Looks like some of the MLB stadiums in recent years.
Of course, the MLB has a lot more weekday games, so presumably, people are at work. But, many stadiums have many vacant seats even at night and weekend games.
Maybe, it is just better viewing at home or at a sports bar with a big widescreen to watch, instead of fighting the crowd and traffic, etc.
And being disarmed and searched without warrant.
Baseball plays 162 games. Only the tiny stadiums regularly sell out. But that still means about six or seven tes more tickets sold.
