I am a certified "SF Geezer" (74yrs). There are numerous reasons for the passing of SF old culture. The first being most natives with roots moved out. We were also inundated with "Elsewhereins" for another. We could fill pages on the why's. As for or city accents my favorites were listening to the accents of oldtime Irish and Italian guys spinning tales in the sauna at the venerable South End Rowing Club in the late '60's. They were on their out. What neat, special guys. I should have recorded many.
