There is only one problem. It just isnt true (as far as I can tell) - nowhere does it say you need a passport to travel between US states-
January 8, 2007 Passports will be required for ALL air and sea travel to and from Canada, Mexico, Central and South America, the Caribbean, and Bermuda. This includes children of any age. Children will not be allowed to travel under their parents passport. Travel to the above areas prior to Dec.31, 2006 and return to U.S. in 2007 also requires a passport.
January 1, 2008 Passports will be required for ALL land border crossings as well as air and sea travel.

timeline
In the proposed implementation plan, the requirement will be rolled out in the following phases:
* On January 8, 2007, U.S. citizens traveling by air between the U.S. and Canada, Mexico, Central and South America, the Caribbean, and Bermuda will be required to present a valid U.S. passport, Air NEXUS card, or U.S. Coast Guard Merchant Mariner Document.
* It is anticipated that on January 1, 2008, U.S. citizens traveling between the U.S. and Canada, Mexico, Central and South America, the Caribbean, and Bermuda by land or sea (including ferries), may be required to present a valid U.S. passport or other documents as determined by the Department of Homeland Security. While recent legislative changes may permit a later deadline, both the Departments of State and Homeland Security are working to put all requirements in place by the original deadline. Advance notice will be provided to enable the public meet the land/sea border requirement.
Travel Documents for U.S. Citizens
Under the proposed implementation plan, the following documents will be acceptable to fulfill document requirements under the Western Hemisphere Travel Initiative:
* U.S. Passport: U.S. citizens may present a valid U.S. passport when traveling via air between the U.S. and Canada, Mexico, Central and South America, the Caribbean, and Bermuda, and may also use a U.S. passport to when traveling via sea and land borders (including ferry crossings).
* The Passport Card (also referred to as the PASS Card): This limited-use passport in card format is currently under development and will be available for use for travel only via land or sea (including ferries) between the U.S. and Canada, Mexico, the Caribbean, and Bermuda. Similar in size to a credit card, it will fit easily into a wallet.
* We anticipate that these documents will continue to be acceptable for their current travel uses under WHTI: SENTRI, NEXUS, FAST, and the U.S. Coast Guard Merchant Mariner Document. As proposed, members of the U.S. Armed Forces on active duty traveling orders will continue to be exempt from the passport requirement.
