Friends summer is here! Be careful of the heat. Stay hydrated all day. Brad Sutherland and I have gone the Camelback Hydration System route. This is a bladder of 70oz. or 100oz. carried on the back. Put your Gatorade or water in the bladder in the refrigerator the night before and it says cool up til around noon. You can find units at the Outdoor World on Ravenswood Road or get them off the web site, www.blackhawkindustries.com.
