a second frame rotatably coupled to the first frame, the second frame including:
a front member proximate to the front end and extending transversely relative to the cross member; and
a rear member proximate to the rear end and extending transversely relative to the cross member;
a vertically oriented first post with a first aperture located proximate to a proximal end of the first post;
