So a friend and I have a week, in late february, with which we plan to drive around TX, NM, AZ, etc. We're starting and ending in Dallas, from Sunday the 17th until Sunday the 24th. I'm from Seattle, she's from Milwaukee/Chicago, and neither one of us really knows much about the area, other than we want to see some awesome ghost towns, tourist traps, and UFO-related whatevers. I've found all kinds of good stuff online, what would you all recommend? We have a rental car and a shared dislike of rigorously scheduled vacations. Suggestions?
