Sounds like a bunch of cars of various types show at the Chick-fil-A (sp?) near the Dulles Town Center. I'm in the local Saab club, too, and a bunch of those guys sound like they're getting together every Friday evening if the weather is good. I haven't been yet, but it sounds like there's a cool mix if American, Euro and Japanese cars show up.
