The mountains or the desert would not seem the appropriate places to escape terrorists who have trained in Hindu Kush area (Afghanistan/Pakistan) and who may be from places like Saudi Arabia, Libya, Syria, etc, etc, etc. Maybe the deep woods of the lower rockies would bother them, since trees would surely be a mystery to them. Or we could chase them across the Great Plains, and harvest them like so much wheat or corn (might even be able to devise an armored combine with a special head to do the job :) )
Never underestimate all those farmers and others out here who are proficient with a scoped rifle. Whitetail at 200-300 yards is no problem.
