Seema Mehta | (TNS) Los Angeles Times SCOTTSDALE, Ariz. — Michele Pitek moved to Arizona from California, her lifelong home, with her husband, Mike, about seven years ago in part because they were tired of struggling with the cost of living in the Bay Area despite both earning six-figure salaries. Once they settled into a newly built home on more than an acre at the edge of Scottsdale with stunning views of rocky peaks, Pitek, 57, said there were some adjustments: learning to depend on a septic tank, treating well water that contains arsenic, for instance, or seeing John Deere bulldozers pull into the parking lots of shopping centers.
