Power bars are a good quikie and they make them where they actually taste good now. Sometimes you have a destination to make by a certain time and rather than stop, the power bars are great for a temporary quik fix while enroute. When hunting with a pack/ gear and equipment its easy to burn 3-4 hundred calories an hour and I pack away the gatoraide also and drink up to 6 quarts a day depending on conditions. Not only does it help in replacing body fluids but also helps in muscle spasms such as charlie horses, something you young whipper snappers think happen to other people. A good ole p/j sandwich is loaded with protein as well as a banana/peanut butter sandwich. I keep it in a tupperware container to keep scent away from the critters and especially from the ole griz. Good luck, Bobby
