Cover up

When going out into the woods, it's a good idea to make sure you dress properly. Even if it's hot, you want to make sure your legs and arms are covered. Ususally, if you pick a light fabric, this will be enough to ward off an unwanted encounter with poison ivy. One other benefit is that you will also generally ward off unwanted pests such as mosquitos and biting flies as well. The best poison ivy cure is to stay away from it in the first place!
