This is a virtual cache located in the Hiroshima Peace Park. Since material cache items aren't really appropriate for the theme of this cache, a virtual one has been placed instead.
The question is, "what is located at this virtual cache location?"
To score a find for this virtual cache, you MUST take a picture of yourself and your GPS infront of the object located at the cache coordinates and upload it with your find. Any logs that do not contain a photo of you and your GPS at the plague will be removed.
