AURAL PLEASURES: MARKET STREET MUSIC FESTIVAL
If the live music at the Stern Grove and Yerba Buena Gardens Festivals make you sad that most weekdays are quiet, the annual People in Plazas festival should help fill in any remaining gaps in your work-week concert schedule. This free July-to-October Market Street music festival puts on more than 145 free lunchtime concerts of all types in 16 different public plazas from the Embarcadero through the Castro.
FRIDAY NIGHT SKATE
Rather than plunking down a big portion of your salary (or unemployment check) on a gym membership (or signing up for a free introductory pass at a different gym each week: a.k.a. "gym slutting"), get sweaty by donning your blades or old-school roller skates and join the Midnight Rollers' weekly Friday Night Skate. A large group of skaters embark from the Ferry Plaza on a 10-mile dance party/skate tour of the city, which includes plenty of stops for ice cream, Frisbee-throwing, and a chance for slowpokes to catch up.
Macy's Union Square puts on free monthly cooking demonstrations in the Cellar, where top local chefs reveal their secrets for dishing up creative yet healthy meals. Not only do you get to learn skills like how to barbecue like a grill master, expertly pair chocolate and wine, or make a brunch worth waking up early for, you also get to sample the yummy delights the experts have cooked up.
