The posted coordinates will NOT take you to the final geocache container. They will take you to the Scotts Hospital building. It was opened around 1925 as a private hospital. It was closed in 1931 and converted to apartments when the new county hospital was built. A very neat and historic building in Sanford.
To find the final for this mystery cache, you will need to complete two Adventure Labs.
"Two Towns COLLIDE! - Sanford: Part 1" and
"Two Towns COLLIDE! - Jonesboro: Part 2"
At the end of each of the 10 stages you will get a number that will help you solve for the final location of this bonus cache. If you missed any after completion, the numbers will be located in your journal.
Final Coordinates = N 35 AB.CDE W 79 VW.XYZ

You can validate your puzzle solution with certitude.
A big CONGRATULATIONS to Night-Hawk on his FTF!
