Sep. 9, 2015 The Hundred Degree Solution

I talked with someone yesterday in downtown San Francisco who said it was one hundred degrees Fahrenheit. His office is an old building that does not have air conditioning. Instead, it has windows you can open for fresh air, including transoms over the doors. Sometimes a simple old idea works just fine. Now he has to worry about pigeons flying through the windows, but they might be useful for messages.
