I'm deeply offended that you decided to lump in my town in the Bay Area with the rest of the West Coast. There's an astounding difference in culture between it and San Diego. /s Seriously, though, at some point we have to group regions together. All American cities have more similarities than differences. Regions do share some commonalities. I'm not sure what you expect from this piece. The author mentions that there are differences between the various cities in the region, contrasting Detroit with Cleveland. Should he have gone into more detail?
