AS USUAL, THE CACHE IS NOT AT THESE COORDINATES.
This is the first cache in a series honouring some of Wellington's geocaching characters.
Yeetrees is one of the stalwarts of the Wellington geocachers. The number of caches he has found (many with the help of Mrs Yeetrees) is in the five figure range, the only problem is, he doesn't always log them. He also has a FTF in every month since he started caching 
. He has placed many caches to be found, from Camborne Walkway (Wellington) to "Arenophilia" (Wellington). Thanks Yeetrees.
On 1st January 2008, Yeetrees found his first cache Pencarrow Head (Wellington), which also was the old Pencarrow Lighthouse's 149th birthday. So today, 1st January 2018, marks not only the old Pencarrow Lighthouse's 159th birthday, but also the 10th anniversary of geocaching for Yeetrees.
He has been known to go out in the wee hours to be the FTF (Mrs Yeetrees will attest to that 
), so I wonder, who will be the FTF for this cache? Yeetrees himself, Huhugrub, Mr-Mcgoo, Boxhill, -gonefishing-, GSEL, CaligulaNZ, or ..........
So, let the fun begin!!
Another logic brain buster for your solving pleasure!
Something Yeetrees likes doing!!
Eliminate the necessary squares on the grid. See this link for help.
When you are done, add up the numeric values of the square you eliminated by row. Then from top to bottom, create a numeric string with all of these row totals (it should be over 10 digits long) and enter it into the checker below.
You can validate your puzzle solution with certitude.
