At the above coordinates, there is a memorial site for the Vietnam veterans. Look first for the one that references Fern Docs. Multiply the second to last digit of the date on that plaque by 55 and subtract that from the above latitude. (For example, if the number was 9 that would be 9 x 55=495. Then as follows, 26.368-495 for 25.873) Then, count the number of names on this same plaque and multiply that times 6. Subtract that from the longitude.
You may want to pull past the soccer fields to parking at N 41 26.150 W 72 47.099. At the base of a field, this is a convenient place to access the loop from. Alternatively, if parking at the fields is taken up, there is a pull off on Tyler Mill Rd at N41 25.905 W72 46.982 (this lets you bypass some of the muddier trail but unfortunately, also some of the ridge). From here the blue trail will intersect the ridge trail at N41 25.951 W72 46.987 to access the ridge.
You will be looking for a micro on the ridge. Because it is hidden on a ridge, it is not too far from the trail. Please take care to hide exactly as found to minimize muggle interference 
. On the back of one of the log sheets, you will find the coordinates for the latitude of the nearby unknown cache "Peace in Our Time".
PLEASE bring your own pen for this one.
The path in from the soccer fields will be muddy in spring, hunting is allowed in season and the ridge is most certainly beyond the abilities of most smaller children. There are pretty veiws of Wallingford from the ridge top! I am not adding the biking attribute but I did see tire tracks everytime I did this hike.
