At the listed coordinates you will find a memorial bench with a view.
In order to figure out the North coordinates you need the number of letters in the 1st word of the 3rd line. Add that number to the original North coords.
In order to figure out the West coordinates you will need three numbers and you will need to subtract those three numbers (as a 3 digit number) from your original West coords. The first digit you need is the number of the letters in the 1st word. The 2nd digit you need is the number of letters in his 1st name. The 3rd digit you need is the number of letters in the last word. Subtract that 3 digit number from the original West coords.
