Color your world

Or at least, have campers carry trash bags that are colored brightly. Once lost, these bags could be used as a device to signal to the others your location. Also, the bags could be used during an emergency like when it is cold outside and they need temporary shelter. Simply cut a slit at the bag’s top and have it pull through the head. Believe it or not, this plastic bag could serve as an effective albeit temporary protection that could keep a kid camper alive through the night.
