The right to travel?

VeloNews legal columnist Bob Mionske has written a very interesting and insightful column on the legal precedent for the "right to travel":
The Constitutional "right to travel" is a funny creature. Everyone knows it exists, but no one seems to know where-it is not explicitly stated, and one federal judge found that at one time or another, the Supreme Court had attributed seven different clauses of the constitution as the source of that right. To make things even more complicated, the ‘right of travel" really isn't a right of travel-it is more accurately described as a right of migration from one state to another without interference. However, in a 1972 Pennsylvania case involving a teenage "cruising" ban, a federal judge said that there truly is such thing as "the right to go where you want" . . .
