I found this spill powerful and very true -- wonderful presentation
(i wish all communities had affordable and plentiful public transportation like the San Francisco Bay Area. Their BART system was a godsend for many living in the poorer cities but worked in the affluent areas -- heck i recall a Field Trip my High School Physcis' Prof took us to UC Berkeley via the BART from Daly City, CA)
Cal was my first choice when i graduated from High School but i didn't even get an invite to visit and ended up at UCLA (i visited campuses in Oregon, Florida and Texas, as well as a few in California)
I miss the Bay Area. I have an X who lives in San Carlos (she grew up in Pacifica.
So You know exactly what i am talking about with respect to the Public Transportation!!
San Diego came close with their Trolley line but the wealthy communities blocked the construction and so not all of the county is united / linked.
