shade tree, lawn chair, cooler full of cold adult beverages, OH you said at work.. LOL if its like last year here just seemed like everything broke right out in the middle of the jobsite or there wasn't even a cool breeze to be found. I have a plastic squirrel cage fan I keep on the truck, for the most part I just work thru it might take a break more often if its really hot. I keep a big water cooler on the truck along with a regular cooler with gator aid in it!! ( I can only handle the taste of water for a little bit I know its good for me but just don't like it) I don't run the AC on the truck till I know im headed to the house either. I also have the large brimmed hard hats to keep the sun off of my neck/ears. last summer I helped a ol cat work on a few things on a job south of here that had a roll up sunshade made up that was attached to the side of his truck & rolled out like on the side of a camper that was just great to work under as long as he didn't need the crane... I always think of my dad when people talk bout stayin cool, he wore long sleeved cotton shirt & bib overalls all year long(he was a welder starting out in the 40s), always said "sweating is good for you, it gets rid of the poison in your system" must be something to it he was still working at 85!!!
