Man, I miss Charleston, you're lucky! Also, if it's the same show I was looking at today, it was rescheduled to the 15th-16th. Maybe you can make that? I'll definitely be there at least one of the days trying to spend some money.
*Edit* Looks like there's one in Richmond (which I assume is the one you'd be referring to) and one in Norfolk. Norfolk was originally the 1st-2nd and Richmond originally the 15th-16th. Looks like they flip flopped their dates. Either way, I'll keep an eye out for the ammo.
