i freeze bottles of water, i change my clothes to my hunting clothes once i get to my stand, then i throw my wet/sweaty clothes in a ziploc....i bring a battery operated fan too, between 2-4 that puppy is on, i just dont care if it spooks deer or not, if i'm passed out from heat stroke or something , then i wont be able to hunt anyway, lol......when it comes to the deer, i just get it out as quick as possible....field dressing is an option as well.....get all those warm guts out of it...you can take a thin rope or a shoelace to tie the stomache together after gutting so that no dirt gets in....ok, so less dirt gets in , lol.....
