Pretty much the same thing for me. I go from condo to car in covered garage. From covered garage to office and then back again. I do get out a good bit at lunch, as there are lots of places to eat within walking distance. But the truth be told I could probably wear a flannel suit, wool socks and boots to the office most days of the summer and not suffer much. I work in a newly constructed, LEED certified building, the temperature is precisely controlled by zone so that no portion of the office is ever any more, or any less than 72 degrees. It's as if seasons don't exist. That, however, takes the fun out of dressing for the season and the variety it creates. IMO offices should be something more like 75 in the summer and 65 in the winter - but that would be unAmerican, wouldn't it?
