Last year I volunteeered in a Swiss alpine garden for three weeks. One of our projects was to help build a pond.
Now that I’m home I’ve actually been to visit the Lobster Haven Ponds and seen a giant freshwater cray. An old one can grow up to one meter in length.
One of the lovely things about this facility is that it is run entirely by volunteers. They also have a little cafe and you can sit on the couch with your Devonshire tea gazing out over the rich and fertile surrounding farmland. Perfect really!
