Yeah, I have no idea what the cost would be to fix the sound system.
I do know that flat screen tvs are incredibly cheap and they could easily upgrade all of the tvs next to the concession stands and under the overhangs in the back of the lower level and club level for well under $50K. Half of the tvs don't work and the ones that do all look terrible because they are the world's oldest flat screens. Super easy fix.
Structure wise it has looked good to me.
With Covid and low attendance they have really skimped on the amenities...reduced choices and quality of concessions, lots of stands closed, "express" lines that are slower than the regular lines, etc. And of course this happens simultaneously with the ban on bringing in outside food.
