well, personally, I'm all for cloning dinosaurs and sabretooth tigers from the frozen DNA we have.
I think the first place we turn them loose should be Washington, DC...approx. where the US Fish and Wildlife HQ and Department of the Interior, National Park Service, and the Capitol Building.
We can then move them around to different areas as required from there, beginning with San Francisco and the state of MA
That ought to take care of most of our problems.
