These Caches where placed by PAR_Frank meaning Paul, Amanda and our Son Ryan who came with on the adventure of planting the series.
This is one cache in a series of "FILM CONTAINERS" hidden along the Lake Emily walking trails. Most of which are "hangers." Inside the containers, look for a letter in the cap. Record which cache contained which letter. These letters will be used to find the coordinates of a Final Lake Emily Cache.
The series could be completed in a day, including the final.
The "Hint" is in the Title.
