No where in the Constitution is the Right to "Freedom to Travel" issue mentioned. In the late 1700s, this Right had been so widely accepted since the Magna Carta that the anti-Federalist never even conceived it to be a necessary addition to the Bill of Rights.
The pdf in the following link details the gradual restrictions of the "Freedom to Travel" using passport control as the means of restricting travel in and out of the country.http://mises.org/journals/lar/pdfs/2_2/2_2_8.pdf
Internal travel has gradually been restricted by the requirements for driver and vehicle licenses and insurance as well as the recent increase in use of internal roadblock/checkpoints.
William N. Grigg has some interesting points on the subject of Freedom to Travel in his article dated Monday, September 14, 2009 titled Helot on Wheels
After his sarcastic opening line "What an unalloyed blessing it is to live under a government describing itself as a constitutional republic!" he proceeds to describe how restricted and dangerous American travel has become, soley because of the meddling of various levels of governments and sums up with the following statement.
"All of this is the noxious fruit of a diseased tree -- namely, the whole system of licensure governing the 'privilege' of operating a motor vehicle. This is among the nastiest versions of the familiar trick in which government redefines a right -- in this case, freedom to travel
, which is recognized in Anglo-Saxon Common Law at least as far back as Runnymede
-- into a revocable 'privilege'."
"What this means in practice is that traffic police are distant but unmistakable kindred to the Krypteia, a cadre of bully-boy secret police who were authorized to lurk at roadside to prey on the enslaved Helots, plundering and killing them at will."
"Accordingly, the moment any of us steers a car onto a public street or highway, he becomes a Helot on Wheels, as it were."Any new Constitution should EXPLICITLY FORBID ANY INFRINGEMENT of an individual's Right and Freedom to Travel, both inside and outside the country.
