So that is what I'm talking about. LA may not have hundred of highrise housing projects nor 1000s of miles of subway tract (but we do have more subway miles than CHicago and almost as many rail miles even though we started in 1990, not 1890). LA may not be as subjectively urban as NY, Cleveland, Pittsburg, buffalo, but it say it is not urban is serious denial. LA offers the chance to live in one of the vanguard cities. It has excitement and a vibe that you won't find in Toledo, Cincy, Chicago, BUffalo, etc. Plus UCLA and Keck are in the heart of the urban collusus of LA, so that is why they belong with NYU, COlumbia, and UCSF.
