I'm in the preliminary stages of planning a road trip in June 2014 and I wanted to run the possible route by you to see how long you think I realistically need to achieve it, and whether it may need trimming down. My first idea is this:
Tuscon (have to visit a friend there)
The best route 1 stops
Having read through a few threads, it seems like this could be over-ambitious, though I could very likely have 3 to 4 weeks available for this.
