On a recent trip to Europe, the most important piece of paper
in my travel wallet turned out not to be my driver's licence, my
Visa card, or even my passport, but a laminated sheet of yoga
poses torn from the back of Travel Yoga: Stretches for
Planes, Trains, Automobiles and More! by Darrin Zeer
(Chronicle Books, $12.95). It didn't help me rent a car, secure a
hotel room, or cross a border, but it may well have kept me out
of prison for the murder of incompetent airline baggage
handlers.
