I'm planning on seeing a friend in Denver, but I'd like to see a part of the country I have never seen--the Rockies. I thought it might be a good idea to fly into a major Western city (Salt Lake, Las Vegas, Los Angeles) and then rent a car to take to Denver. I'd like to see a few of the great American sites but also some tucked away parts of the country. I don't want to spend more than two to three days so Los Angeles probably wouldn't be wise....or would it? Anyone have any ideas? What sites are really worth seeing and what is just hype?
