I think my In Laws took 4 months or so. But they'd stop and do every little ole thing. I traveled about 800mi a day. But I was by myself. Couldn't get the ole lady to go. Seriously if this is a one time thing and you want to see it all, you need to be able to take all the time you can. It's wide and vastI am thinking maybe two weeks is not enough to make this trip. I am working on the map compiling the info will get this sorted and come up with a bette timeline.
