When I was a very young lad, we holidayed on Valentia Island, just off the Kerry coast. I still have memories of seeing a sow and her numerous porky offspring resting in the kitchen of a farmhouse. At the time, I didn’t think much about it. On reflection, they were much simpler times and we kids were happy sleeping three to a bed in our holiday home. There was no internet, no television, one channel on the radio and only a small river to amuse us children.
