This checkin to GC827X6 2019-01-08 51 -1, 09:19 reflects a geocaching.com log entry. See more of Dan's cache logs.
Thanks for the report, Team Hippo. Given the lack of activity and the usual thoroughness of the previous cacher, I’m going to choose to assume that this cache is inaccessible until I can get out there in person to check on it/perform maintenance.
