Bay seniors tracking the movement of hipsterdom may have noticed it’s moving south down Third Street into Bayview. Sample the changes this Sunday at the Speakeasy Brewery where from 12 to 6 locals will celebrating Oktoberfest. 60 vendors will be serving up DIY arts and crafts as well as beer in some inventive forms – beer mustards, beer cheeses, etc. Free. While you’re in the neighborhood stop by Flora Grubb the dazzling nursery that is responsible for the rebounding popularity of succulents. The nearby, spiffily restored 1888 Bay View Opera House is definitely worth a visit.
