I have no idea what you mean by persuasions. Typo? Do you mean "precautions"?Any persuasions I should take?
If you will doing several of the major photo opps in the Southwest, consider getting the 3 volume set of paperbacks named Photographing the Southwest by Laurent Martres. The 3 volumes start in Las Vegas and go through Utah, Colorado, and New Mexico. The books should be required reading for anyone with a camera headed to the Southwest.
