The object of these larger sized Sudoku puzzles is to place
the numerals 0 through 9 and letters A through F in a 16 x
16 grid so that each row, each column and each 4 x 4 grid
contains each number and letter one time only. Yellow is North Green is West
There is no reason to go through the woods off of the main trail. There is a trail further down that will go almost to the cache. No need for bush whacking.
Congrats to altbiers on FTF! There is a FTF coin for the FTF.
I rated difficulty 3.5 because the puzzle is a little hard and I rated terrain 2.5 because of the long hike to the cache.
