You are expected to physically sign the log sheet in order to log your find on-line.
I archived the NFC POC cache here at OCC due to its high maintenance to find ratio. I salvaged one of the locations for this cache.
OCC is mapped, including trails, on OpenStreetMap (OSM). You can see this through Geocaching.com by selecting Set Map Preferences button on the map side panel. Next select Leaflet from the pop-up. Then in the upper right corner of the map, select OpenStreetMap Default from the map choices.
