Summer, without a doubt! The heat and humidity here just kill me. I've been threatening to move to the Rockies or something the last two summers. A lot of days I don't even leave the house to go to the mailbox. I'll start having symptoms after just a few minutes outside, or even inside if it's not cool enough. I actually had to get up and give a little speech at church about the necessity of turning the A/C down a bit, because I really couldn't take off any more clothes, while anyone who was too cool could certainly put some more on. I was having to get up and leave before the service was over every Sunday. So now we have a "cool" side and a "warm" side!
