Commenter Dennis sends this picture noting:
There was a Yogi Bear's at the corner of Two Notch & Decker. Where K-Mart's parking lot is.
This sign is actually in Hartsville, and the store there is about the last one in the US. The one in Columbia had a sign identical to this one.

UPDATE 22 June 2010 -- I get a lot of hits looking for Yogi Bear's Honey Fried Chicken. Just for fun, here are two pictures (like Dennis's above) from what I believe is the last Yogi Bear's still in operation. It's located in Hartsville South Carolina at 514 South 5th Street:
