I've been digging through threads and most of the accessory info I've read is for winter/cold weather and how to keep from freezing yer rump off. I live in the south where cold weather is defined as "not humid" and it can get down right unbearable to sleep in at times- you can only take off so much clothing.

I was wondering what other hangers did to keep cool during the dog days. I've been looking into getting a small portable battery operated fan i could possibly hang from a ridge line and have it shooting deliciously cool air (more like thick and muggy but beggars can't be choosers) as i sleep but I've not been able to turn up anything from my search here and virtually everything i found shopping seems to be too heavy and bulky. Anyone have an suggestions or experience with certain portable fans or other means of keeping it cool during the long summer nights?
