This thread is awesome.. My husband and I are going to the US in late July for 4 weeks. We fly into San Francisco and are there for 4 days so I have found the Arcatraz and Muir Woods travel tips to be very handy. After San Francisco we are flying to San Diego catching the train to LA then flying to Las Vegas for 2 nights before starting a 7 day road trip. After our 7 days driving we are flying to New York (not sure where from yet, hoping for some great opinions) to visit a friend for a week before flying home.
We will hire a car but we are finding it hard to choose where to go. Everything I have read puts Denver Colorado at the top of my list, but from there we are not sure. Our first thought was to drive to Chicago but I have read that the drive is boring after you get past Denver. Now we are thinking about doing a big triangle - Las Vegas - Denver - Yellowstone - Las Vegas. Any suggestions? We dont mind doing a few long drives if we need to as we both will take turns driving.
