You won't find the bench you are looking for at the posted coordinates. The degrees are correct but you'll have to adjust the minutes as described below.
So what is this, just another magnetic keyholder under a bench? Not exactly. You are looking for:
3/16/2011: Sadly, somebody took the cute wooden bench that was hidden 'inside' the tree. So the 'cash' is no longer under a bench hence the new title.
That's nice and all but to get the coordinates, you'll need to solve the rebus below. From that you should be able to come up with a 6 letter word. Take the first 3 letters, convert them to digits using the following conversion: a=1, b=2, c=3, ..., i=9, j=0, k=1, ..., z=6. Divide the result by 1000 and add them to the posted minutes of the latitude. Repeat with the last 3 letters and add them to the posted minutes of the longitude.
Congratulations to TheScottFamilyFive on the FTF!
