This is recommended to be done at night, to see the stages lit up. However, it can be done at all times.
You will need to complete the Light Me Up Columbus! Adventure Lab Cache in order to gain the correct coordinates for this puzzle cache. The Geocaching Adventure Lab App will need to be downloaded in order to complete the AL. The difficulty, I rated a 3, due to needing a smartphone app. The posted coordinates, just take you to a well-lit and wordy spot in downtown CBUS.
Note: Because the Adventure Lab defaults to a "finished" screen, you may miss the final coordinates, but they are there. Just go back into the lab page, scroll down and click on VIEW 5 JOURNAL ENTRIES to find the bonus cache info.
You are looking for a nano on a sign post, at a location that I prefer to see in the evening, all lit up. But truthfully, its pretty cool in the daytime too. Great spot for photos.
You must finish the Adventure Lab to get the final coords to this puzzle, a bonus physical cache.
