We are thinking about a driving trip from Baton Rouge through Austin to Santa Fe and perhaps the Grand Canyon. The goal will be to see what we can of the historic Indian sites and perhaps go up to Shiprock. I last went through this area as a kid, and that was 50 years ago. Flagstaff was barely a wide spot in the road and Grand Canyon was not very crowded. I have some Kodachromes I shot on that trip, but little memory of anything. I would like to do some photography on the way, subject to my wife's patience. What would folks familiar with the area recommend putting on our destination list? Canyon de Chelly is a must see. This will be in mid-May - is that the best time?
