The white pioneers credited with founding Seattle is known as the Denny Party. The name of the ship which delivered this group to Alki Beach was a schooner called "Exact" - hence the name of this cache. That was in November 1851. Of course, there were already native Americans living around these parts. 
The voyage of the Exact was pretty rough with ill travelers low on supplies. And we all know how November tends to be around these parts. May your passage to this cache not be anywhere as trying as theirs was and may your growlers be well-stocked.
Use the code phrase you find inside the container with the people inside ... you may get a little treat. All managers know about the geocache.
Please return the cache components exactly like this. Thanks!
