This is the bonus cache from the Wherigo, May the 4th Be With You! GC85PVV. The only way to obtain the final coordinates for this cache is by completing the Wherigo. Once you have completed that cartridge, you will be able to extract the coordinates for this cache, which is within 1/2 mile of the Wherigo final. In order to obtain that information you will need a smartphone with an NFC reader app loaded onto it. I have tested this with an app called "NFC Reader" but there are plenty of apps to choose from that have the same functionality.
Please do not try to remove the cache from its hiding spot. The cache opens up from the bottom. It easily unscrews so you can retrieve the log. Also, do not try and retrieve this cache from the main road. You should be able to park very close to this cache in a parking lot without approaching from the main road.
Good luck and May the 4th be with you!
