Part of this story is that the teams have evolved in terms of ‘cost’ and the Oakland doesn’t have enough people who are willing to pay out $300 for two people to attend a game, park their car, or take care of beer/food. I could have told you that back in the late 1990s when cost was ramping up.
Vegas? If they are smart, there will be over 300 party rooms on the main deck areas...with guests to lounge around and watch the game.
Saw a World Series game there in 74. Few years later saw several Concerts there . I imagine it’s a run down dump . Locally there is a 50 year old venue that is crumbling, but the city kicks the can down the road. So it goes.
