driving from death valley to monument valley (or vice versa)

Thanks for those very useful replies! We've been all over the US also, just never the far southwest. We're starting in the fall in SC, then Hot Springs NP, family in Nebraska, Great Sand Dunes NP, Mesa Verde NP, Moab to see Arches and Canyonlands NPs, Red Rock Canyon outside Vegas, Death Valley NP, Monument Valley, Grand Canyon, Meteor Crater, Petrified Forest NP, then home. Whew! Just got tired writing all that! But can't wait to get started! Thanks again!
