Thanks to Ike (hahaha...), I have a couple extra weeks of vacation, so... roadtrip!!!

My preliminary plan:

Austin, TX --> Big Bend NP --> Petrified Forest NP --> Grand Canyon NP --> Yosemite NP --> (maybe: King's Canyon and Sequoia NP) --> (maybe: Joshua Tree NP) --> Phoenix --> Saguaro NP --> back to Austin, TX

Any ideas and/or suggestions to places along/near the route that I should visit? Any good food places I should pay a visit?

Thanks.
