I'll be in the Bay Area the weekend of 5/11-5/13. I'll be guest lecturing at a class at CCSF that Friday, and am otherwise pretty wide open. I plan to visit all the genre bookstores I can while I'm there, but am otherwise open to suggestions.
...I still have a Dastardly Plan™ to take you to the Cheese Board when you're in town for WesterCon; but since you'll be in Berkeley, you might want to have zhaneel69 take you there instead, given that you'd then experience it's glory two months sooner.
I certainly wouldn't mind tagging along, though. You & frankwu are always much fun to hang out with.
