This next instalment in my Cache Phrases series is a follow-up to my Partridge Family tribute series of letterbox hides. As mentioned in the listing for those 7 caches, watching The Partridge Family television show was a regular habit for me after school, with both the new and repeated episodes being highly anticipated. It may have only lasted a few seasons, but the repeated viewing were certainly effective: I remember the lyrics to several of the songs to this day!
Although it is not necessary to have done all of the letterboxes in order to solve the puzzle, at least have a look at the listings: you never know what useful information you may find.
Shirley
Keith
Laurie
Danny
Chris
Tracy
Reuben
In order to get the final coordinates, you will need to do some math:
[Laurie + Tracy] . [Chris - Shirley] [Reuben - (2 x Laurie)] [Keith + Danny]
[(Chris x Shirley) - (Reuben + Danny)] [(Keith x Shirley) - Tracy] . [Reuben - Shirley] [Chris - Laurie] [(Tracy + Chris + Keith) - (Reuben + Shirley)]
Trailhead info is in the geochecker.
