Even more great ideas, eCasa!
I like making the circle in front of the SAC the center of campus. Put up a clocktower, something.
ESS is getting kinda rain-stained too and its ugly. I also agree about the lots, but i figure thats an uphill battle as professors wont want to walk far (laziness). Commuters will go nutso about that too. Centralization is a great idea though.
