An old how-to guide of how to effectively blow up a horse has resurfaced, leaving many scratching their heads and confused over how such a situation would ever occur. The guide, first released by the USDA Forest Service in 1995, comes complete with illustrations in case the need to blow up a horse ever actually comes about. The guide, which was published for Forest Service employees, reveals that sometimes you just have to blow up a horse. But why? Well, the guide also explains that. Dead animals left in park or recreation areas may attract bears. …The guide also advises parks employees to remove any horseshoes the animal may be wearing… to reduce the possibility of flying metal bits of shrapnel. …Thanks Forest Service.
