The above coordinates are bogus. There is nothing there regarding this cache. It's just a big parking lot. The final is located somewhere within a 20 mile radius of the bogus coordinates in Spokane County.
Spokane, Spokane. It's a pretty big place. It currently, and has been for a long time, the largest city between Seattle, WA and Minneapolis, MN. A lot of people live here (418,000 + in the metro area), and some of the best cachers around are among them.
There are many different sights around town, that I'm sure all of us take for granted or are so use to seeing that we now never even glance at them. Perhaps we are too busy fighting rush hour traffic that we never quite saw that mural, or that interesting piece of architecture.
Let's find out who pays attention to this city. The locals may have a leg up on this one, but tourist are always welcomed to play...
Down below you will see several pictures of different items. The key is to take those items and figure out which map they are located within. Then you throw all that into this equation N 4a bc.def W 117 gh.ijk keeping in mind that Spokane County is a pretty big place and we are evil and not to take the "norm" for granted.
For example, if picture "a" is of the big red wagon in Riverfront Park, then "a" in the equation would equal 3 because the big red wagon would be in map three below. Note: "a" is not of the big red wagon in Riverfront Park...
