COOLEST DAY IN HISTORY:  On this date in 1902, Willis Haviland Carrier completed his design for the modern air conditioner.  God bless him.  I still remember the day the house where I grew up in Virginia got air conditioning.  I was probably about nine years old.

Here’s a reminder of how much difference air conditioning has made:    In 1900, Phoenix’s population was 5,544; today the Phoenix metro area has 4,652,000 people–an unthinkable number without Carrier’s invention.  This afternoon, the temperature in Phoenix is expected to reach 110 degrees.
