My husband and I will be driving a car out to our daughter at Arizona State U. in August. Any tips on how to go about this, places to see on the way (we want to see an interesting sight or two...). We can only take a week or so, so it will be driving, driving, driving, but is there any place along the way that's a 'shouldn't miss'? Any tips on better routes, or highways to avoid? Thanks SO much... my dh put me in charge of this...
