Tlaquepaque is also in Sedona - a marketplace with many unique shops. There is a great quilt shop in Sedona...... If you are interested in riding a train through the Verde Canyon - you can do this in Cottonwood, Arizona. Of course the Hoover Dam on the border of Arizona/Nevada is wonderful to visit. There are so many great places to visit in the southwest - have a fantastic trip. Some of the best tips for local sights to see can be discovered by asking the local folks in the area that you are visiting.
