Police in Industry said the 49-year-old man was standing by a tree when he was hit by a bolt of lightning at about 8:30 p.m. Saturday.
Industry officer Aaron Lopez said the man and others were moving Scouts and camping supplies off the site as a thunderstorm approached.
Lopez said no children were nearby when the man was struck. The man was up and walking around when police arrived, though he was treated later at Heritage Valley Hospital in Brighton Township for a wound where the lightning bolt apparently exited his body.
Police are not identifying the man.
