One thing about Fosston is that there are not many caches. While in town for work I had an idea for a cache with a little history involved...and maybe some math and counting. So, here it is.
When you reach the posted coordinates use the information to solve the for the coordinates to the cache location.
N 47 zz.abc W 095 xx.dyy
a = number of people standing on the wood pile - 1
b = number of water towers
c = year on the ball -1910
d = how many 's' in the town name?
xx = year established - 1840
yy = number of original towns
zz = number on the train + 2
once you have all the information you can start your search for the cache. You are looking for a bison tube.
We hope this is enjoyable
