I got that same email. It was the 1st that I heard about the event. All I know is that it's at the McClellan Air Museum. If you've never been there .. its has a nice set up. I don't know if I'll be going. I too checked the ES site and did not see it listed??
Did you know about this event on 3 June? I've registered for it.
