We had 6 weeks and arrived and departed at L.A international visiting California, Arizona, New Mexico (briefly), Colorado, Utah and Nevada. Saw all the usual hot spots Disneyland, Vagas, Grand Canyon, Hoover Dam Petrified Forest, Giant Sequoias, Yosemite, Monument Valley, etc and some off the track sites like Canyon De Chelly, 4 corners Nat. Park, record frog jumps at Angel's Camp, frozen lakes west of Lake Tahoe just before the end of the winter season. Had our daughter's birthday 3 April 2013 on the edge of Lake Tahoe. Learnt some interesting history about the Navajo Code Breakers roll in W.W.11, etc,etc. No room to tell it all.
Generally, we had a great time and will return.
