Many of the writers suggested leaving the fly off of the tent. I check my weather radio before retiring to make sure nothing is brewing. As you know, when it is hottest and muggiest, frequently it portends a brewing storm. But, if it seems OK, I will put the fly half on, leaving the upwind side exposed. The other half can be left loose or tied to trees on the upwind side. This acts like a funnel to direct any light breeze on me. If rain does come, since half the fly is on, it only takes a couple of minutes to attach the remaining side. 8-)
