Benny Boy, actually, the more you look like Che, the better off you are
in 'mi querido Mexico.' A buzz cut is classic gringo. Entering with long
hair and a Kombi (they call them all Kombi down there)is to your benefit.A
Che sticker on your Vanagon is a great idea too! Now, re-entering the USA
will be the exact opposite of course. So wait until your return trip to
buzz your hair, shave off all those stinkin liberal bumper stickers from
your vehicle and paste a big ol NRA sticker on your rear glass.
Buena Suerte!! Miguel
