James Hunter of the Pajarito Grotto in New Mexico says that they can now get vehicle permits and windshield stickers for Mexico at the Mexican Consulate in Albuquerque. That is apparently also true in Austin and Dallas. That would be a tremendous time saver at the border. Even better, it looks like you can apply for your vehicle permit by Internet and have it mailed to you! See <http://www.aduanas.sat.gob.mx/aduana_mexico/2008/index.html>. Click on English at the top, then select Passengers arriving by land, then Where can you obtain the permit? and How much does it cost and how do I pay?. It costs more at the consulates than at the border, and even more by Internet, but I think the time saved would be well worth it.
