How do you store your power supply extension cord

Our 50A cord is a Bohemith and 45 ft. long. It won't fit in a bucket, wheel well, Milk Crate or Laundry Basket so I use the mid-size one of these sold at the Orange Big Box Store. It leaves enough room inside to store a regular 20A extension cord, Surge protector and a couple of towels to wipe the cords off if they get muddy.
