I want a new stadium absolutely. It would be way easier for me if they put it in downtown LA in LA Live, but I'd be ok with them building a new stadium in the parking lot. Maybe finally bring the Big A back into the OF. Short porch in RF where balls can land on the 57. Call those "Traffic Shots" or something. Hah.
Either way, they need to build around the stadium more too. Put in a downtown type atmosphere. Tons of bars and restaurants to go pre game at so we aren't limited to OC Sports Grill, Hooters, and The Catch. Give it that SF/SD feel.
