The NVA/DC metro area would be a great place for a regional, but there are no obvious locations that I can think of. The GMU Patriot Center is not big enough for a regional, unless they have a LOT of extra floor space hidden in the back for the pits. The seats are all nonmovable. The MCI center appears to be the same way.
The DC Convention Center has the space, but not the seating.
An interesting side note, the
MCI Center and the
Patriot Center have the same website.
