The one in Eden was Mar. 1. It's by NC vintage bicycle assoc. Reidsville show is usually Sept. sponsored by Reidsville bicycle. They have a website also. One in Charlotte too, but not sure when. These are usually posted in events section.
Working with the owner of the bicycle museum here in Mount Airy to try to put this show back together. We have a location but my opinion is that it isn't large enough so we are still looking. If all goes well it will likely be in October again.
