About 20 young farmers attended the first of a three-day workshop about using draft horses on their farm. As the fuel and equipment costs continue to rise, many farmers are looking for more sustainable and economical sources of farm power, a media release about the class said. Over the three days, beginning farmers will learn the basics of horse care, ground driving, hitching and teamwork. Participants will also consider how horses fit into a larger farm business plan as both an expense and potential income stream — from logging to sleigh rides.
