I have been thinking about JoeBob's post about needing his BOB bag and he said something about taking interstate hiways to leave out in a hurry. A vet that works with the state police told me several years ago, that, in the case of a major incident in the United States that the Interstates would be closed to the general public and used only for the Military/Feds. Also that the reason that there are flat straight stretches every so many miles was to be able to use them as temporary landing strips/airbases. Has anyone out there know anything about this?
