My first thought was that the states that border a given state should always be able to be put into a circular order. If A borders B, there should always be exactly two states that border both A and B. If I start with one of them and look at states that border A and this new state, I should keep getting a succession of different states that border A, until I return to B, and there should be no bordering states unaccounted for or duplicated.
I'm not exactly sure but Wisconsin is a bit of a problem: it is bordered by Michigan, Illinois, Iowa, Minnesota and Exterior. But Michigan doesn't border Illinois. /Bernie\ -- Bernie Cosell Fantasy Farm Fibers mailto:bernie@fantasyfarm.com Pearisburg, VA --> Too many people, too few sheep <--
