A cover assembly (14) has a lower section (16) in a cylindrical configuration. The cover assembly has an upper section (18) in a conical configuration. The cover assembly has an intermediate section (20). The lower section has an open lower end (22). The upper section has an open upper end (28). A base (38) is in a flat circular configuration. The base is movable between a closed orientation in contact with the lower end of the lower section and an open orientation spaced from the lower end of the lower section. A strap assembly couples the cover assembly and the base securing the base in the closed orientation and releasing the base from the closed orientation.
