This is a challenge cache. The cache is at the stated coordinates, but you cannot log it as a find until you have completed the requirements. To fulfill those requirements, you must have logged at least 100 caches in each of three US states, one of which must be Vermont. Please use the provided checker to prove your qualifications. 
This is another in the VT 100 century challenges, which lie along or near VT 100, a scenic byway that meanders mostly north and south through many beautiful vistas and small towns in Vermont. The road is not for the faint of heart, and the challenges aren't either. While the hides are not meant to be difficult, to qualify for the challenge it takes a certain amount persistence, and travel.
This challenge is meant to encourage cachers to reach out beyond their own borders. You must have logged at least 100 caches in each of three states, and one must be Vermont. For this challenge, state means US State, of the 50 represented by stars on our flag, and not DC, Puerto Rico, or any of the other territories.
If you enjoy this challenge, there are many of them in this series, along VT 100, although you may find them more populated further north. There are also many other great challenges to look for both in Vermont, and in those other states you are already caching in. Not to mention the rest of the world.
This cache takes you to a historic corner and building still in use in South Londonderry. While the D and T would usually be in the 1.5 range, your D is bumped for the minimum 300 caches required to qualify, and the T reflects the winter hazards you may encounter depending on conditions. It is not wheel chair friendly and you might need a stick or other tool in snow.
The cache is a pill bottle big enough for small tradeables. Congrats to BevanQ for FTF.
Do NOT park along Rt 100. If there is no parking at the historical society, look for trailhead parking just beyond.
