I thought I would pass along a good hydration tool that we went to. We bought Camelbak water packs for everyone. They are miniture back packs that hold water and have a tube that hangs over your shoulder for drinking. They are designed for the outdoors and work great, a whole lot better than the water cooler at then end of each lawn stuff. The best part is that at the beginning of the day we put only ice into them. As the ice melts you drink the water. Meanwhile you have a nice "ice pack" sitting in the center of your back keeping you cool. Just thought I would pass it on.
