Carrie and Richard Levine describe themselves as vagabonds. During the past 15 years of their marriage they have lived in six different cities around the country. Two years ago, Richard's work brought them to Scottsdale, Ariz., where they found their dream home in a desert mountain preserve. Both are fortunate enough to work from home--he is a software contractor who also writes science-fiction novels, and she is a resource manager for a global consulting firm. They have decided to move near Carrie's family in Tampa, Fla., and have started their house hunt online. Real estate agent Barbara Bailey is also helping. They've given themselves one weekend to find a new home in their new city. Will they find it before their time in Florida is up?
