The retroreflective surfaces may comprise an entire outside surface of the hunting structure or fire hydrant caps, or it may comprise only a portion of the outside surface. Because of their retroreflective properties, both the hunting structures and the fire hydrant caps may be seen more easily. Because retroreflective liquid coating, powder coating, or tape is to be used, these designs are inexpensive, easy to install, and environmentally friendly. | 09-01-2011 |
