The Richmond show is pretty small, and for the life of me I can't find any info on it either, though it should be coming up soon. I'll look for my last copy of Reptiles magazine to see if I can find it.
The best show for you to come to would be the one in Raleigh, NC in May. Kathy Love will be there she said, I don't know about Rich yet. You usually will have some of the bigger breeders there, Alex Hue, Ben Seigel, etc. And they always have a f/t vendor or two there so I stock up on mice while I'm there.
