This is a simple Letterbox cache.
At the posted coordinates you will see 2 light blue Sea Containers located on my farm. From the sideroad you can easily see the large font identification tags (4 letters, 7 digits ) on them.
Subract the number found on the smaller container from the number found on the larger container to obtain a 6 digit number. Call this number ABCDEF
The cache can be found [A/F][C-A][C-B] meters on a bearing of [E-D][C-E][E-F] degrees from the posted coords.
Please leave the Stamp in the cache container. It is not a trading item.
The neighbours near the posted and the final coordinates are fully aware of the cache.
