Zip Over to Cal Anderson Park on Saturday

Zipcar just emailed us about their activities and festivities planned for this Saturday. The day begins with do-gooding: after assembling at Cal Anderson Park at 12:30 p.m., they're going to pick up litter on East Pine Street from 1-3. Then it's back to the park for the rest of the "Sounds Outside" concert, complete with Zipcar picnic snacks, park games, and special treats like driving credit for all members. (As per usual, if you recruit someone impressionable to the Zipcar agenda, you get extra credit.) If you want to help out, RSVP to cleanseattle (at) zipcar.com. Here's the full Sounds Outside lineup: 1:00 p.m. Figeater; 2:30 p.m. Industrial Jazz Group; 4:00 p.m. Greg Sinibaldi; 5:30 p.m. Syncopated Taint Horn Quartet; 7:00 p.m. Bert Wilson.
