About four years ago I was working on a landscaping project on a horse farm in West Tisbury. Word quickly spread around the farm that a horse had lain down and died in its stall that morning. There was somberness in the air on that hot summer day, with the humidity promising a thunderstorm in our near future. Horses are not small creatures, and a front-end loader was brought in to extract the animal from the barn. The scene became quite loud as chains were rigged this way and that and the engine on the machine was revved for more power.
