FIG. 3 is a front elevational view thereof;
FIG. 4 is a back elevational view thereof;
FIG. 5 is a top plan view thereof;
FIG. 6 is a side elevational view thereof with a stirrup entering the cover;
FIG. 7 is a side elevational view thereof with a stirrup in the cover and a boot poised to enter the back of the cover and through the stirrup; and,
