I don't get out past the airport to South Congaree much at all. I used to drive out every now and then in the 1970s to see if the South Congaree Book Exchange were open (it never was), and I think I drove through there on the way to AIken once. It still seems to be a pretty rural area, without much urban advance (though quite a nice Food Lion has made it there).
This particular building is on the west side of the road before you get to Food Lion (coming from the airport). I neglected to look for a street address, and google suggests a number of different possibilities (some of which may be previous or later locations for the same business).
UPDATE 31 March 2011: Added a full street address based on the comments. Apparently Edmund Highway is Main Street within South Congaree city limits.
