Hey Kent, Nice that you had 3 weeks! Not many people get that chance. Considering the country is only about the size of Kentucky, it is not as much driving as it might appear. Believe me, people will see plenty.
Considering you know the place, check out the blogs from some of the past trips and you might see some familiar places.
Thanks for the comment!
