His real name is Wally Marshall, but he goes by "Mr. Crappie." The weekend of October 4-6, he's bringing what he calls 'the biggest Crappie Tournament and Expo' to Hot Springs. Taught to fish by his Grandmother, Wally is an angler, sportsman and a promoter. The Expo will feature a giant free crappie fry. On the heels of the FLW Bass Tournament in Hot Springs earlier this year, Lake Hamilton will again play host to anglers. This time, 100 two-man teams will take to the water in search of $100,000 in prize money.
