A flexible panel member is provided including upright horizontally spaced apart and elongated sides interconnected along their lower marginal edge portions by a bottom extending between and anchored relative to the side lower marginal edge portions. An upstanding end wall extends and is secured between at least the lower portions of the sides at one pair of corresponding ends thereof and the upper marginal edge portions of the sides include stiffening members extending therealong from at least areas thereof spaced centrally intermediate the opposite ends of the sides toward the aforementioned first pair of ends thereof. The second pair of corresponding ends of the sides are at least substantially free of connections extending therebetween above the bottom and the portions of the stiffening members supported from the longitudinal central areas of the upper marginal edges of the sides include structure defining elongated horizontal hand grips extending longitudinally of the sides. The bottom is downwardly inclined toward the first pair of corresponding ends of the sides when the hand grips are horizontally disposed.
