Uh...lead in ground? Of course there is lead in the ground, and on the surface, and on the rocks, and on most every bit of trash there. What would using a rake disturb? Lead dust comes from firing, not the chunks laying about.
"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself...A murderer is less to fear. The traitor is the plague."......Cicero
