Ooh! Not Halloween yet but you scared me. Spent lots of time in the big, U.S. West Coast cities and found them not much different than big cities (admittedly, L.A. is a little different) anywhere in the world - yes, and being a white man. Two years back, some nice, not-white folks went far out of their way to help me get a flat fixed in Portland. I offered some cash later, in appreciation and they wouldn't take it. Survived in Chicago, too. Parts of that city are wonderful and the people were delightful. Maybe you get what you give.
