Watermelon? How about pond-melon?
Should you find yourself on the road near Columbia with some time to spare, maybe swing by Yandle's Roadside Market to see what 177 pounds of watermelon looks like.
The State has the better photos and report that I've seen; get it here.
The market is at 407 S. Assembly Street, a smidge south of downtown.
