Excess packaging just bothers me so little thingies of food in lots of wrapper annoy my sensibilities - but I love PowerBars. Of course bananas are already perfectly wrapped... and I have Gatorade in the water bottle and water in the Camelbak. (Gatorade from the powdered concentrate, of course - and I use the old containers for coins and screws and nuts and stuff )

Mostly I stop to eat along the way, though...
