Hi, my wife and I are looking to drive to San Francisco. We have 4 days to drive from Philadelphia to San Francisco spend 4 days in San Francisco and then 4 days to drive back to Philadelphia. I'm aware that we are going to spend most of the time driving, but we want to see as much scenery as possible. Was thinking, PA to San Francisco through Colorado on the way out, and San Francisco to PA through Wyoming on the way back. I'm aware this is ambitious, but luckily we both function very well on little sleep. Looking for thoughts and suggestions Thanks!
