Oh I hope you’re right. I think that should be a universal rule at all sporting events: If you’re not there 1/4 of the way into the game, anyone can move into your seats. The way I see it, if you don’t care enough to get there a quarter of the way into the contest, then you don’t care about where you sit either.
So yes, everyone buy GA tickets and move down. There’s always a couple seats to my immediate right.
