I live in Iowa City, Iowa and a few friends and I are thinking about taking a roadtrip out west and then down south to visit a few of our friends. We want to go from Iowa City->Denver->Salt Lake City->Portland->Los Angeles->New Orleans and then finally back up to iowa City. We would like to spend one day in each city and drive at night because we will all be able to share driving duties. Any thoughts on whether this is a good idea and if it is even possible?
