THE CACHE IS NOT AT THE POSTED COORDINATES,
but you will need these coordinates to solve the puzzle.
The posted coordinates will take you to a plaque by the trail. This spot has two uses: first, you will exit the trail here to make the find, and second, you will need to wish Bob a Happy Birthday at Bob's place.
To find the final coordinates you will need to do a little research first.
Find out what YEAR the "Great Big Baked Potato" made its first journey across the country.
That year will be AAAA
Subtract 1888 from AAAA, and add this number to the last 3 digits of the North coordinates.
Next,
you will need to find out what YEAR the last train ran(same year as the tracks were abandoned) on the tracks that the Foothills Trail now occupies.
That year will be BBBB
Subtract 1967 from BBBB, and subtract this number from the last 3 digits of the West coordinates.
Now you should have the coordinates for the final.
