I have heard those same concerns. But when you look at the geology in where this drilling is done and you have the layers of Marcellus, and I think you only fracture maybe 18 inches, perhaps, from that horizontal pipeline, so you haven't permeated the entire Marcellus shale, and that is encased with a layer of perhaps hundreds of yards thick, hundreds of feet thick, at a minimum, of limestone. The geology is very, very--it's almost--you never say ``never,'' but it's impossible in order to get that what would be called migration for that fluid to move outside.
