That's John and his wife. They had some sort of tiff with the Silverado management several years and don't do those shows any more. He's regularly at the Chantilly show, however, as well as most PA shows.
Very nice couple with good merchandise.
Met up with John at the Chantilly show today and told him about this thread. He noted that he never had any issues with the Silverado shows or management, so I stand corrected on that. He did, however, have issues with the Appalachian shows after Top Hat retired, and mostly he got tired of the Maryland laws that hinder his making a living, so he rarely (if ever) does Maryland shows any more. He's usually at the Chantilly show, as well as some of the Pennsylvania shows like the Oaks show.
He also offered to make a deal with anyone who purchases some of his stuff if you mention this thread!
