I live in a sparsely populated area. I don't think there are enough "goats" to adequately cover one end of the state to the other end. Do you think Joe Hoober will arrange buses to transport the soon to be slaughtered from the densely populated cities to rural areas for scriptural fulfillment? Perhaps the birds will carry some of the carcasses to suitably spread the slain from one end of the earth to the other end? And what about the oceans that separate the continents, perhaps there will need to be rafts of slain bodies to complete the slain-stretching-end-to-end-of-the-earth prophecy?
Well, Jesus did say that faith the size of a mustard seed could transplant mountains. So I suppose it will be up to the remaining dubs to fultill this prophecy. They will simply exersize their faith in their Lords and Saviours, the Governing Body of the Watchtower Bible and Tract Society, to transplant several million bodies from large metropolitan areas such as New York over to Idaho, Wyoming and such. It'll put a whole new spin on "it's raining men!" In order to cover the seas, there are nowhere near enough people on earth to do that, so perhaps Joe Hoober will whip up some handy-dandy floating dead bodies from scratch and send them off on their maiden circumnavigation of the globe. Since the Internet is a tool of the Devil, perhaps we will communicate with distant friends in the New System by placing messages in the mouths of these floating carcasses and shoving 'em out to sea. They'll be like very slow passenger pigeons, but hey nobody will be in a hurry in the noo system.
EDIT: On the other hand, there could be a completely different interpretation. Perhaps it just means that Joe Hoober will "spread those slain from one end of the earth to the other" by dismembering them and scattering the body parts evenly over the globe, just as he lovingly commanded that levite to do in the book of Judges.
As for the life raft, you might want to invest in one of these:
The rubber tent-roof will protect you from Joe Hoover's fireballs as you set sail for Paradise on a sea of boiling blood! Praise Jah!
