This one will be a bit tougher multi. You will need to use a few tools to complete this one. One is simply, your brain, but the others are up to you to figure out. Therefore, I had to put the difficulty up there.
Look 200 feet at 178 degrees from where you are parked.
Using only the large letters of the name you see, using a tool that you have, convert each of the letters to numbers and then add them up. and subtract the total of this number from the posted West coordinates. Checksum: Last 3 digits of West will equal 12.
Now look 200 feet at 72 degrees from where you are parked.
Using only the large letters of the name you see, using a tool that you have, convert each of the letters to numbers and then add them up and subtract 17, then add the total of this number to the posted North coordinates. Checksum: Last 3 digits of North will equal 15.
