First, of course, is to maximize disposable income — the amount left after paying for housing, utilities, taxes, and other necessities. Second, he likes cold weather and enjoys winter sports.

Here are descriptions of the three job offers:

• Madison Publishing in Minnesota. Disposable income estimate: $1300 to $1500 per month. Snowfall range: 100 to 400 cm per year Magazine score for evaluate quality of the community: 75. (out of 100).
• Pandemonium Pizza in California. Disposable income estimate: $1200 per month.
  Snowfall range: almost none, Magazine score for evaluate quality of the
  community: 95. (out of 100).
