Ditto the yup. During hot weather, Bubba would be collapsed on the side of the road without electrolyte replacement. I've bonked because my body can't digest "real" food on long or hot climbs, and can't say I like sulfur-induced asthma from dried fruit.

Not sure why the wrapping on an energy bar is any more wasteful than the gooey bag leftover from a PBJ or whatever "real food" snack.
