1. Scottsdale, Ariz. What does $150,000 buy you in Scottsdale? The average home, but also a near-spotless safety record that really wowed the folks at Parents. Low crime and low unemployment, coupled with a branch of the Mayo Clinic right in its backyard, make Scottsdale one giant security blanket for expectant parents. It gets powerfully hot during the summer, but average high temperatures that flirt with 70 even in December and January provide year-round access to 67 miles of paved trails, 105 miles of bike lanes and 22 playgrounds with baby swings. -- Written by Jason Notte in Boston. >To contact the writer of this article, click here: Jason Notte. >To follow the writer on Twitter, go to http://twitter.com/notteham. >To submit a news tip, send an email to: email@example.com.
