Attention! Attention! Los Feliz Village is on the verge of invasion. The mild-mannered hamlet, whose own community association proclaims it “America’s Hippest Neighborhood” (thereby instantly diluting any such hipness), is prepping to be overrun by thousands this Sunday during the 14th Annual Los Feliz Village Street Fair, which will take place from 11 a.m. to 5:30 p.m. between Franklin and Hollywood on Vermont Avenue. It is alleged there will be live entertainment, artisan booths, rides, raffles prizes, games, food and fun for the kids ó perhaps even a petting zoo with a real live zebra. You have been forewarned. Proceed with reckless abandon at your own risk. That is all.
