Abandoned Textile Mill
This mill is definitely shut down and has not been operational since 1976. A vast majority of it has been demolished as a major fire ravaged it in 2000, right before I moved here. Perhaps you are thinking of the Mayo Mill in Rockingham County, NC? (http://www.chriscrowder.com/avalon/story4.php)
The mill is or the name is? That's a pretty dead looking structure in Michael's picture.
This mill is still owned and working by a textile mill company.
