Jack Latimer wants Hall County to know about a piece of history before it’s gone. Latimer and Edward Hardman are taking apart an unassuming tin-roof barn that skirts the edge of Ga. 82 on the way to Jackson County. While it doesn’t sound like much, the barn is a bit of a mystery and could be one of the oldest structures standing in the county. And in a few days, the pre-Civil War building will be gone.
