The first stage is located on a public road outside a very unique museum, and should be findable without leaving your vehicle. It is not necessary to enter the museum or grounds to complete this cache. The second stage is a short drive away, in a cemetery, and is therefore accessible during daylight hours only.
Use the following key to decode the clues:
A=1 B=2 C=3 D=4 E=5 F=6 G=7 H=8 I=9 J=0
K=1 L=2 M=3 N=4 O=5 P=6 Q=7 R=8 S=9 T=0
U=1 V=2 W=3 X=4 Y=5 Z=6
At the posted coordinates, look for a NO OUTLET sign. On the same post, below the NO OUTLET sign, is another white, rectangular sign with a 17-letter message. Use the key to decode the following:
a = first letter minus seventh letter
b = seventeenth letter
c = sixth letter minus sixteenth letter
x = fourth letter
y = second letter
z = second letter plus fourth letter
