The county has been delaying and excusing the inevitable for almost a decade now. It's embarrassing. Worse, it's becoming a hazard. Whole chunks of the Astrodome are falling off now and the concrete entryways are too dangerous to walk on.
I understand the historical significance to the Astrodome, but it is not that old. It's just a shell made of concrete and steel, less than 50 years old. And like a lot of architecture from the 1960s it is extraordinarily ugly.
Just get the inevitable over with. Tear it down, make the crater into a nice plaza. Quit dragging out what we all know is coming.
