Best not to visit on a Sunday or Saturday night during mass. However, at all other times, cache should be easily accessible without Muggle threat.
Easy park and grab except during regularly schedule mass times (and funerals? weddings?). This church has a lot of history. Plan a little extra time to walk around the one-room building by the road. Historical marker explains it all. The container is a micro -- please use caution to REPLACE THE CONTAINER EXACTLY AS YOU FOUND IT. I've lost one container already, and I lost the original log with it. :( Be kind....put it back exactly the same.
