Roger, Not placing one location above the other, but if you haven't seen the
west in the USA I highly recommend it. I prefer small mountain streams
myself but I think Pennsylvania is sweet. However, 'do not' go to the
western clave without two days planned for sightseeing. It's really, really
neat.

As a loyal Pensylvania native, I must second John's advice. At the
very least, fly into Denver, rent a car, and drive up over Trail Ridge
Road in Rocky Mountain National Park, on to Salt Lake City, then hop a
flight to the Clave.

Others are welcome to modify, contradict, or ridicule this advice, but
it would be a shame for you to see the spectacular beauty of the
Rockies only from 35,000 feet.
