Sherri Gerrin, from Liberty Farms in Clarkesville, is no stranger to uncommon-looking produce. Every time she cuts into one of the large casaba melons, customers ask, “What’s that?” “About the only way to sell them is to cut one up and them try it, because they’re afraid they’re buying something they won’t like,” said Gerrin, who is one of several farmers who lines tables and fills baskets with familiar and nontraditional fruits and vegetables at The Original Hall County Farmers Market in Gainesville.
