This is the first I've heard of it, but I just downloaded the app and there is a couple near our house on the dog walks. One seems to be the converted-to-house-church at the end of our road.
Next time we're walking the dogs I'll see what happens when I get there. I might need to read up, I don't really understand what I'm supposed to do... like I have an inventory of items, but I don't know what they're for
