SATURDAY:

As Jake Slogged earlier, there's a big immigration reform rally and march that you should go to. (Judkins Park, 2150 South Norman Street, noon.)

The Ballard URban Picnic, or "BURP," features mobile food trucks ready to feed you, a beer garden, live music, and a screening of the Disney film "Up" at dusk. (Ballard Commons Park, 5701 22nd Avenue NW, noon to 9:00 p.m., free.)

It's Free Comic Book Day, so go get some free comics, already. (Participating comic shops, everywhere, free.)

SUNDAY:

More marching and rallying, this time from Seattle University to Waterfront Park to abolish nuclear weapons. (Seattle University's Quad, 1:30 p.m.)

Seattle Center is holding a Seattle Mural Restoration Open House to celebrate the mural and bribe you to vote for it in the "Partners in Preservation" contest. Can you be bribed with cake and live music by Slender Means, or are you going to let Tacoma's "Schooner Adventuress" (the current leader in the contest) win? (Seattle Center Mural Amphitheatre, noon to 5:00 p.m., free.)
