The Weaver House is over a century old. There is lots of information on signs here about its history, and about what went on here during the early 20th century. Check out the sign about the Styx Hall. During prohibition, people used to hide their liquor in trees out in the nearby woods. Kinda sounds like an early version of geocaching!
The first stage starts at one of the informational signs. To find the next stage, you must get some numbers from the sign. This is a four stage hide, so two more to find before the final.
2nd stage coordinates are N42 54.ABC W86 10.DEF where
A = last digit of the year the first property was aquired.
B = (winter closing time) - D
C = (3rd digit of phone number - not including area code) / 2
D = last digit of the year The Weaver House was built
E = (winter closing time) / 2
F = (last digit of # acres) / 3.
