I'm not sure what goes on in C-Burg or B-burg on the 4th, but there likely is something. I do know that Roanoke has a celebration the evening of the 4th. A concert by the Roanoke Symphony that culminates in fireworks.
I'm in Floyd County, not to far from C-burg. My brother is coming in on the 4th and we are loading our GSs on a trailer to take to VIR. We are also doing the CLASS on the 5th.
I'll look around and see what is going on locally for the 4th.
