NY to CA but not straight.

[Fintripper]

Hello all,

We are 4 Finnish wannabe Road-trippers :) We started to plan a coast-to-coast road trip for next summer (2009). Now i wanted to get some input on whether our plan is doable, and this forum seems just the right place for that ;) So here it goes:

Planning on renting a car for a month and driving a route which could possibly go like this (see the attachment):

1. New York
2. Through Smoky mountains to Atlanta
3. To New Orleans
4. To Memphis to see Graceland
5. To Sioux City to see some native american stuff
6. To Mt. Rushmore
7. To Utah and Salt Lake City
8. Through Grand Canyon to Las Vegas
9. To Los Angeles

Now my question is, is this a doable / viable route to do in a month? TripTik gives around 4700 miles for the whole route (70 hrs driving time), and when all the other driving is calculated there, its probably around 6000 miles. Is TripTik anywhere near right on those driving hours and do you think this route is good?
