Good ideas! And Jo I hear you about the weather. It is so humid sometimes that it feels like you're swimming through the air, not walking, huh?
I do like to open the door and let air in (snakes are now in what would be used by normal people as the "breakfast nook" of the kitchen, near a french door.) And yes, a fan sounds like an idea as well.. I plan on melting more holes in the tubs this weekend. I saw one person on here who had a ton of holes in their tubs and thought, huh? But now that seems like the way to go!
