This cache was designed to see how well you pay attention to the things around you. These things may be obvious to some and "hidden" to others.
I did not design it to be hard but think that it will be so it is getting a high difficulty rating. No hints as that would make this mental test of no use.
Now on to the cache info:
At the first way point you will need to locate the three missing digits for the second way point which is at: 47.39.xxx 122.40.989
At the second way point you will (hopefully) find the coordinates for the third way point.
At the third way point you will (see how positive I am) find the coordinates for the final!
DO NOT POST ANY PICTURES OF ANY OF THE WAY POINTS!!!
