For fairies, I think

I found this tiny sign in the corner of the campground we are staying at. I have no idea why it’s here or what use it is.
We are staying in a NZ motor caravan campground in Welcome Bay which is a suburb of Tauranga. We had a frost this morning and a beautiful day. Some of the ground is soggy from recent rain.
The extra is a photo of our caravan (2nd from the left).
