Yoel, bad timing...
I'm actually travelling myself to the states at the end of the months for several weeks and will be in San Francisco on 4/29. Was hoping we could catch up there... Oh, well.
Regarding wine events there will be a wine festival at Jerusalem's botanical garden right before Shavuot that you might like to check out.
