The epicenter of the neighborhood luminaria fest that started on Holly Street in the early '90s has moved to the corner of California and Buena. A woman up there--Betsy, don't know her last name--started organizing her block around '98 or '99. Other blocks followed, usually organized by people Betsy knows, until now there are 30 or 40 blocks involved.
Anyway, the California Street tradition is a little different from ours just a block to the west. The folks get together in the mid-afternoon, fold bags and put them out on the street. In fact, almost all the blocks except ours on Holly are done and ready to light by sundown. Last year, in fact, people were coming by our street and asking if we did the luminaria any more. Anyway--very cool to see the activity spread to all the places it has.
