When Rhule mentioned grass in Memorial I printed out a picture of the stadium and surrounding areas and used a Gerber adjustable ruler to take measurements. Since they are tearing down South Stadium anyway, if the field were grass and were put on rollers and rolled to the south, and if T street were permanently closed, the field could butt up against Manter Hall and the very NE corner of Richards Hall. The parking lot north of Manter Hall would be lost. It they did this there would still be around 15 yards of the field remaining in the stadium. But if they wanted to have concerts or motocross races or whatever, that last 15 yards of field remaining in the stadium could be easily walled off. The field would have to be rolled back into the stadium the next day so it would get sun again. And some kind of enclosure would have to be built to protect the field not covered by the new South Stadium (between South Stadium and Manter Hall).
It could be done, it would just take some resolve (and money).
