The Danvers/Peabody Rail trail was once a part of the B&M (Boston and Maine) Railroad system. As recently as the late 1990s I remember seeing the tracks being used for freight, the tracks were later turned into a trail that goes through Peabody and Danvers.
Please remember to be respectful and follow the rules of the Danvers/Peabody railtrail. This includes: No smoking or fires, no alcohol, no motorized vehicles, and no trespassing on private property.
The cache container is a small lock and lock with room for trackables. The hint is a sure giveaway so try not to use it unless your brain is frying and you can small the bacon. STEALTH IS REQUIRED.... hence 2.5 difficulty.
