A soldier guards a marijuana plantation discovered near San Quintin in Baja California state, Mexico, Friday, July 15, 2011. Soldiers have found the largest marijuana plantation ever detected in Mexico, a huge field covering almost 300 acres (120 hectares), covered by shaded netting, the Defense Department said Thursday. The plantation is four times larger than the previous record discovery by authorities at a ranch in northern Chihuahua state in 1984. (AP Photo/Alexandre Meneghini) less
