These do not have to have been found all in Oregon, nor after the publishing of this cache. 

List this challenge as a part of your list, but it doesn't count towards your total. 

HOWEVER--CHALLENGES ARE EXEMPT FROM THIS unless the challenge itself has a puzzle as a part of its requirements (like this one). 

ANY "unknown" cache that requires you to complete any kind of puzzle to find the final location qualifies.
