There's a comprehensive local discussion about Calhoun's and other Virginia hams
here on eG.
The one I bought last Thanksgiving from the Old Town farmer's market was my first; after a good long soak, it made excellent eating.
Disclaimer: I really don't know much about hams as they are not part of my culture or food heritage. When I married into a Polish family from Cleveland they always ordered one of those pre-cooked spiral cut ones that come delivered in red foil, every Thanksgiving, Christmas and Easter, so until the Calhoun ham, that was my only point of reference.
