I didn't realize little ol' Grandstand sat 6100. A 7000 seat stadium could easily retain the intimacy of Grandstand. Of course, Grandstand wasn't symmetrical, so it got less intimate the further up the tall side you got. I have a feeling the new stadium will have good seats on both sides.
I'm most intrigued by the 3000 seat stadium. This has some real promise if it's a true stadium.
What hasn't been mentioned...
1. will a grounds pass still get you into Armstrong and the 2 new stadiums?
2. more seats means more grounds passes
