Below is the link to a fabulous New York Times article about how not to be crazy on vacation.

We have, perhaps, one of the best bonus benefits as members of 12 step programs...we can easily meet locals in any town and find the best places to eat, and get info on the best non-tourist sights and sounds. I count that as one of my AA blessings.
