Summer is definitely upon the southwest. Not quite 11 AM and the thermometer is already crawling past the 100-degree mark. Some will hit eject to get to a cooler place. There seem, however, to be plenty of people who are happy with the heat. Phoenix, described earlier this year as a place where"the heat is intolerable in the summer, and the city has no defining cultural tradition or obvious reason for existence" just bumped off the city of brotherly love as the 5th largest city in the country. They must sell a lot of real estate in January when it's only 90-degrees outside.
