like most places that rely on trucks (OTR: Over the Road), they will take in products from their manufacturer and/or other manufacturing facilities in order to keep an inventory, build orders, fulfill production line requirements.. etc It's yer basic commerce and Kraft Foods is no different. There are actually several cave entrances around the area shown in this video.

Reasoning behind storing massive amounts of food there, like i mentioned before, it's a natural ice box underground in these caves, it's actually chilly down there in the hot humid Missouri summers.. Cheaper to keep their products cool w/ little to no refrigeration..

One thing I hate about picking up loads out of Kraft is.. IF your trailer has a small hole and or is the slightest bit dirty, they refuse your trailer, then you have to jump back to Joplin, MO and get yer trailer washed out, and return with the receipt proving so.. Otherwise, they refuse you and cancel your load..
