To see a map of the whole trail, check out Lake Wobegon Trail.
So, starting out at the posted coordinates, and facing northwest you will see a big green sign to your left (south of the trail). You can also see what this sign looks like on the cache page, but is has been modified a bit, there are no numbers on it. Also, from the posted coordinates, and still looking northwest you will see a much smaller brown sign to your right (north of the trail), and from this sign you will also need some numbers.
N45 4 A . B
W94 5 C . D
A= the number of "TWO's" on the big green sign.
B= the distance using BOTH signs (Alexandria + the BROWN SIGN) - 2
C= the distance to Sauk Centre.
D= the distance on the BROWN SIGN ONLY multiplied by 6 + 40
Now if you are interested in racing for the gold, check out Pike's Peak hill climb. So, race on out for some Gold.
