Who doesn't enjoy a country drive? We hope this cache draws you to pastoral beauty and impressive, if aging, technology, where you'll get to savor, if you're lucky, wildlife of some sort. The day the cache was hidden, a redtailed hawk dried himself out after a heavy downpour, and three great egrets searched the shallows for sustenance.
To find this multi-cache, go to the given coordinates, where you'll find--pretty much in the middle of nowhere--some handsome numbers. Call those numbers v, w, x, y, and z. Their checksum is 13. Consider the GIVEN COORDINATES N 39 4a.bcd W 77 1e.fgh (that is, a=2, b=2, c=0, d=7, etc.). You need to do some simple math to find out where the second and final stage is located, which is at N 39 4A.BCD W 77 1E.FGH, where
A=a-x
B=(v+x)3-b
C=(z+w)-(v+x)
D=w+x
E=z
F=D-z
G=C-D-A
H=w-y(2+w)
Certitude is for the final stage, if you have a signal and can access it in the field. If not, here are Checksums: for ABCD, 24; for EFGH, 15.
You can validate your puzzle solution with
certitude.
