@dlowan,
I live in the SF neighborhood, and would be more than happy to provide you with some tours in Northern California. I've had the pleasure to meet many a2kers at meets in San Francisco, Chicago, Austin, Houston, London, and Lippstadt.
I have several trips planned for then last half of this year, and the two I know about are cruises in September and end of November. My Canadian friend and I are talking about a trip to Calgary in July.
I might be able to kick up a few a2kers in the SF Bay Area if you decide to come.
