I vote for Santa Barbara, Costanoa or Napa. The only thing with Santa Barbara is I would need to fly there and I wouldn't be able to leave too early in the day. Kevin is taking lots of time off over the next few months, so an extra half day is not a possibility. With that, the last weekend is September is best followed by 9/15-9/16.
I think we should look into Costanoa. I have added dates that I believe Krista and I are open--Shannon please look at those dates and see if there are any that match for you.
8/4-5
8/18-19
or
9/8-9
9/15-16
9/29-30
