Horse shoeing has been called a craft by some and a science by others. Farrier Henry Heymeiring has been shoeing horses for more than 40 years, and describes the trade as an art. The foundation of Heymering's art is his love of the animal. A man of few words and many smiles, Heymeiring's smiles truly convey his passion for his work.
