Yep, it is for sure TIT

. I'm not a big A/C person but will use it when it gets really hot. I grew up in SE Texas/Gulf Coast where it is hot, hot, and hot, oh yea and did I mention humid. We never had an A/C, just fan. I think I was well into my late 20's (and long gone from home) before my parents bought their first A/C. I like the 2nd sheet on top. Feels cool, but will keep the little chill from fan off.
Does help with the mosquitoes a bit, but from what I've seen in Thailand/Udon the mosquitoes ain't nuttin' compared to what we have here. We have several planes that spray to keep the little pricks down to a level that enables us to live. After Hurricane Rita the Air Force had to bring in C-130's to spray, now that was a real mosquitoe killer! Maybe we could get the US to rig up some of the C-130's flying in and out of Udon for a good week or so of spraying. Somehow I don't think so, oh well.
I'll spend some time when I get back in may looking for a "flat" sheet, white will do just fine. Well maybe I better check with wife on the color, hmmm black silk, nah just cotton.
