Cache may, or may not be, at, or somewhere near, the posted coordinates.
Very wheelchair-accessable in the summertime, but not in winter!!
This is not a very difficult cache. Near the posted coordinates, you should see a historical monument. If you don't, you have probably done something wrong. Regroup and try again.
To get the final coordinates, do the following calculations:
A = Number of sides that the sign has lettering on, divided by two.
B = Number of posts the sign is mounted on, multiplied by itself.
XXX = 644 * A (multiply by A)
ZZZ = 933 / B (divide by B)
You will find the final at N44 53.XXX W093 01.ZZZ
Good luck on this swell cache, kids, and don't forget to double-check your math!
