An exploded propane cylinder lies on the grass over 100 yards from a storage yard of a propane plant, after massive explosions overnight in the plant's yard, in Tavares, Florida, July 30, 2013. Dozens of explosions rocked a propane tank servicing plant in central Florida, northwest of Orlando, late on Monday, injuring seven workers, at least three critically, and prompting the evacuation of nearby homes, authorities said.
