Cache is not at the posted coordinates.
Math seems to be one of those subjects that is easy to forget. This geocache requires math that is used in elementary schools. See the picture in the gallery to solve for the coords. Don't mind my not so straight lines, they have nothing to do with it. You could redraw it on your own to solve the puzzle (it would probably be easiest that way). Do not go to the posted coordinates, they are bogus. Don't be afraid to ask for help, but if you have kids in elementary school they could probably help you too.
