Hostess of Options Mystery Cache

The cache container is not at the posted coordinates. That is in the Susquehanna River. Note that the terrain is 2 and not 5. The cache is not in the river. Solve the puzzle to determine the coordinates. Container is in State Gamelands. Wear orange as needed.

As we were driving around the southern parts of Lancaster and York Counties checking out the overlooks of the Susquehanna River, we somehow hit a crazy time warp where all geocaching events from the past 20 years magically became visible. While we couldn't go to them through the curtain of time, we could visit them in our thoughts and sometimes through the pictures on their pages (especially the WWFM Epic Battle). Thank you to each hostess who made these fun events possible over the past 20 years. I'm sure you have great memories of them.

I wondered whether I could create an optimal path to drive between the event locations. Um, no, there are some physical limitations. Do you see how far away some of them are from this cache's posted coordinates despite being hosted by local geocachers? I found this Geocaching Toolbox tool very helpful for calculating distances between points. You need to find only the last three digits of the latitude north and longitude west. The other digits match posted coordinates.

This is a list of 10 events sorted by date:
GC-codes are links to cache pages
