I'm at the Manassas plant right now. Once I get back, I'll be in good ol' Building 500, right off the main plant.

If you're there long enough you might want to check out King's Dominion. It's about an hour south on 95. They have some pretty good rollercoasters there, if you're into that sort of thing. The Grizzly and Anaconda are both classics, and Volcano is a real kick in the pants.
