Obviously, this weekend might belong to Treasure Island for you, which is great — see you there — but we didn't include that because you knew about it. There's also that YACHT concert on Saturday, which SFist spoke to the band about, so that's an option. And, as you may know, it's Litquake! SFist previewed all the fun writerly stuff to do with that, so consult away.
