Sorry, tardiness is a way of life now I'm afraid.
I haven't been to any of those stones, but i'm very aware of them, and they are on the list of places to go see, soon.
Lack of funds, other places, and upheavals at home have curtailed stone hunting somewhat, but blue skies are on the horizon and I might be able to see them sometime this year.
Well done on the Poppy stone, you can consider it your stone.
