Again, I went north. This time I did "Keysoe Klip lock" and "Pertenhall pocket query". 46 caches done today, and while I was out I saw this, next to the bridleway.
Looking at the inscriptions, I think they're all dogs.
I got home very early; I just couldn't see any more caches to do near where I was! So I'll be going out again tomorrow.
