Signs are rather mundane bits of the landscape, they tell one, where to go, what’s up ahead, what something is. And as you know, I do like to take photos of the many varieties of signs, especially when they are somewhat cryptic.

Like this sign here, it is indicating that one can fall, or that one should run in a new direction? Someone has removed part of this sign, perhaps that was the instructions.

I have never heard of such a thing, but it is no doubt helpful if one lives in a city.

This doorway of death seemed to be clearer, there is no smoking, and a giant arrow will kill whosoever enters. Thanks for the warning pal, I will not be entering (Or is this some sort of riddle like Tolkein used in “Lord of the Rings”? I shall ponder this.)

This one is a sort of generalized warning, and is temporary and unofficial. But the pterodactyl seems to be giving this consideration (as that’s what happened to them).

But this venerable sign, carved into the stone of this church, has the best general warning of all: “Commit no Nuisance”. And I think this would cover falling down a shaft, climbing up the side of a building, entering the doorway of death, or causing the climate to change, so this should be universal advice.
