I'm a steady FSU lurker and looking forward to this show. I live in Ashburn, about 20 min from the ION place and have lived in this DC area for many years. There are plenty of restaurants in Leesburg, cheap to expensive. Anyone coming from the north or west shouldn't have traffic problems. Outgoing rush house traffic from the south and east can be the problem. Afternoon Rush hour begins early on Fridays but it's always there. The closer you are to DC, the trickier it can be. Traffic moves better the closer you get to Leesburg.
I'm in Section 102, Row E the end seat18.
