You could carry a collapsable lunch bag and make sandwitches to put in it. They aren't smelly and are easy to make. Also snacks like trail mix. Things like that are good. Just put them in a container and then you don't have to open a noisy bag. For drinks, heck I've drank coffee in the stand b4. LOL! But gatorade, water, and soda's probably don't put off much scent.
