Meteor Crater at exit 233. Don't miss it. And they have a nice little basic RV campground right there, too.
Albuquerque edit: And if you have any interest in things military you should check out this
Nuclear Museum at the south end of town. It's really a fascinating place to wander through, and outside they have lots of military aircraft and other equipment from those years long ago.
