While living in Arizona, our weekends were filled with mini-excursions to various sights. One such trip was to the Petrified Forest. Once there, we ventured only a short distance down a path where we came upon a group of tourists who were listening intently to one individual. We stepped nearer, eager to hear the man’s speech. The self-proclaimed guide continued talking to his audience, “…and to the right is petrified wood. If you’ll look to the left you’ll see a rock. Millions of years ago it was a rock and then it became petrified.”  Petrified of hearing any more incorrect facts, we decided to proceed down the path on our own – sans tourguide!
