At about 10:30 eastern time, a Cessna 152 struck a fence during a precautionary landing in the cow pasture. The student pilot was not injured. The pilot was on the second leg of a solo cross country when the ceiling began dropping. A thunderstorm moved in behind him, so he elected to enter IMC. He momentarily lost control of the airplane, so he descended to just above the treetops. Finally he elected to make a precautionary landing in a field.
