Picture this: We decide to go for a picnic. We assemble food and drinks and maybe a picnic blanket - one of the foldup ones that has its own handle and a nifty pocket on the outside. Not plaid though, a solid color maybe dark green or brown. And flashlights or headlamps because of darkness. We have all of our gear and will get it to the spot how? In a container or containers, right? We unpack everything and the containers we used to haul stuff in is where? Or did we make 5 trips to and from the car and left the empty bag in the car? Do the math. It doesn't add up.
