I want to make a series of 8 geocaches that visit various locations of special interest in a multi-city region. All 8 will have a clue to a 9th BONUS cache, but again in a totally different area of the region. I do not want to register this as a multicache because all 8 are individuals. Nor do I want to list this as a puzzle cache.
My question then is; how do I go about registering the 9th bonus cache so that it will be accepted, without actually entering it as a cache on its own (since I don't want the coordinates, position, etc.) to be displayed?
Do I enter it as a "hidden waypoint" on all 8 of the other cache pages?
If this is normally acceptable, will I not run in to problems with this one because it may be so far away from any of the other caches in the series?
My intention is not to make a multicache series that could be done in an afternoon -- I want this one to take many weeks -- perhaps even a whole "geocaching season", where there is a bonus cache waiting for anyone who puts the time and effort into doing all 8.
My issue therefore isn't really "how" to do it, but rather, how must it be entered for Groundspeak to accept it?
