San Jose is mostly just suburban sprawl. There needs to be more investment in the downtown area, and transit — hopefully BART coming to San Jose in the 2020s will help.
I was just in SF and had to take a meeting in San Jose. The fact that I couldn't take a train all the way down completely blew my mind. What's the point of a commuter rail if it involves an hour bus ride to the other major population center in the region?
