I've lived in Redmond, WA for over 20 years, and the heat acclimatization gained from living in Indiana and North Carolina is long gone. I'm going to <i>try</i> to get that 20 mile run in on Saturday as early as I can, but with an overnight low of 70F I'll probably still melt. That heat pump purchased 18 months ago is starting to look like money well-spent, though. Unfortunately, many/most other folks don't have any form of A/C or cooling. Who needs it when you spend most of the summer wishing it would warm up a bit? :-)<p>I was going to say that I don't recall ever seeing 100F in Seattle, but I guess we did in 2009.
