To escape Wisconsin winter, we're planning a late Jan./Feb. trip. We're thinking of driving to New Orleans and taking a Caribbean cruise from there, then taking a couple more weeks to drive to New Mexico and Arizona. Our main interests there are hiking with beautiful scenery, biking (road, not mountain biking) and playing tennis. We have visited the Grand Canyon in the summer, but have never been to southern Arizona or New Mexico. Any suggestions on sites we shouldn't miss, and where to concentrate our time, considering we're hoping for warm weather, would be appreciated.
