Nancy Drew and her friend Bess were back in Dutchess County this past Fourth of July weekend. While here, they heard the legend of the poor fiddler who met his demise on the way home from playing his fiddle at a dance, and his body was disposed of unceremoniously. The final cache will take you to a place where he might have eventually been found.
At the posted coords, there is a sign on private property (that can be seen from the road) that notes where the poor fiddler met his demise. There are three words in the sign. The number of letters in the first word will equal X, the second word will be Y, and the third word will be Z. The number of letters in the color of the sign will be W. On the back of the nearby warning road sign, there will be a yellow magic number. That plus 1 will be V.
The final coordinates will be N 41 50.ABC W 073 49.DEF.
A = Y - W - V
B = Z - W
C = W + V
D = Z - W
E = X / 2
F = V
Checksum for ABC is 9, for DEF it's 8
