Pete Gaskew, left, and Vicksburg firefighter Andrew Penley watch as a Ford F-150 pickup is towed out of the Yazoo River Diversion Canal near the boat launch at the Vicksburg City Front Monday. Jessie Mitchell of Edwards had just launched his fishing boat around 7:30 a.m. when the emergency brake suddenly gave way. The Vicksburg Fire Department was called in to send a diver out. The truck and trailer were towed out without incident.
