If you're a San Francisco parent in need of additional sitters, Peekadoodle is hosting a "speed-sitting: event on Wednesday, August 29. Like speed-dating (have you ever done that? I have), you'll meet potential sitters for 3 minutes at a time. Anyone you want to hire, you do through Urban Sitters.
The event is free, but RSVP is mandatory. Email your RSVP at firstname.lastname@example.org or call (415) 440-7335. The event is from 7-9 p.m. More info here.
