Sounds like a great trip so far. I am leaving on 20 August for a 3 month tour of the National Parks. I just ordered a 10-22mm for my 20d. I am getting really restless. We have no plans. Just an Atlas and a National Parks pass. It should be really fun. I bought a 1972 Ford Sportsmobile van RV. It looks really great and drives like a dream. I can not wait to see your photos. Rustin
