After exploring for some time at McMillan Creek, FalingintheWoods and I found an old road below the side road that we decided to follow. At the end of the road is a fence and below the fence is a culvert. We followed a path to the side, and were confronted with what we are pretty sure is Pennywise from IT's home....
Note that the geocache is *not* hidden at the culvert, but above, a short ways into the trees and can be accessed from the paved road.
*This cache was hidden for the PGCAR2018 event
