FIG. 1 is a front, perspective view of my design, including a fragmentary view of a water hose portion extending forward from the water tank portion of the design, ready for use;
FIG. 2 is a right side view thereof;
FIG. 3 is a left side view thereof;
FIG. 4 is a top plan view thereof;
FIG. 5 is a bottom plan view thereof;
FIG. 6 is a rear elevational view thereof;
FIG. 7 is a front elevational view thereof;
FIG. 8 is a left side view thereof, showing said water hose portion wrapped around hose support brackets and a watering wand mounted on a distal end of the hose portion stored by attachment to said left side; and,
