Crap, I just realized, you're doing the drive on Tuesday 5/15, aren't you? I have a bridesmaid dress fitting scheduled for 6:30 that day and then American Idol with my mom that night. Sigh. You're still welcome to come by for lunch, or even to stay over if you don't mind getting dragged around. :)
How long will you be in VA? We could make plans sometime for just an evening, like you suggested (after you know your schedule of course) or you could plan to stop over with me on the drive back up.
