Was Fast's Cameras at the same site where Brooks Camera was later? I spent many many hard-earned dollars at Brooks as my interest in photography bloomed after high school. I seem to recall a curly-haired guy who helped manipulate halfway usable prints of my best friend's wedding reception after the negs came out with some weird color cast.
During the time that I recall, the underground health club was Jack LaLanne's. Also, no one has mentioned Doktor Pet Store, on the north side of Winston.
Sometimes I see the old Stonestown in my dreams, but I'm sure what my subconscious conjures up is only vaguely related to reality. But that's generally true of anything else, anyway!
