Welcome to permies Stacey!
My head is full of ideas for a massive veg patch, a proper playground, and space for animals. Currently, however, the hedges are winning and the fences are down!
Is that a kiddies playground, one for adults, or for the animals

? It's a race against time for a veggie patch this year. Do you have much deer presence there, or just the livestock? I'm sure I had a hoiday near Newcastle Emlyn ages ago - is there a woollen mill near you?
It sounds like someone with a tractor could have a fun working holiday, even if things didn't work out long term - good luck!
