My wife and I will be leaving for a trip from New Orleans to Vancouver and back in early June. We will have approximately 8 weeks for this journey. Her family is in Vancouver, so that's going to be about 5-7 days stayover. We have many things that we want to see on this trip and from the beginning of the planning stages, we've been planning a counterclockwise route: major points of interest being; Witchita, Dodge City, Aurora, Cheyenne, Mt. Rushmore, Yellowstone, Glacier, Banff, Vancouver, Washington/Oregon Coast to San Fransisco, Yosemite, Las Vegas, Grand Canyon, Tombstone, Carlsbad, San Antonio, back home (with stops in between whenever something interesting arises). Is this a bit too much to bite off? Will 8 weeks be enough time? Should we take this trip in a clockwise or counterclockwise direction? What will the weather difference be by starting out heading west as opposed to heading north?
