This cache was placed for The Santa Fe 400th Anniversary Event. It is part of a walking tour of the railyard and surrounding area.
The cache is placed near a unique above ground cistern which captures water from the nearby roof tops. The harvested water is used for irrigation of plants within the Railyard Park.
At times this area can be very busy with muggles, so use the hint to be discreet.
Replace it in the same position in which you found it so others will also be able to locate it.
