We returned from an afternoon in Punta del Este to find a new pile of sand (which, here, starts at a depth of 5 cm). I added the concrete top later to halt further work until proper permits were obtained.
The hole was surprisingly large, and the proud culprit was quick to demonstrate it. I thought he would start digging more. Instead, he disappeared underground before re-emerging.
The message seemed to be, See, human? This is how you get out of the heat.
And when you hunker down, no one can see you. Understand now, human?
You should see the tunnel Kiya is digging under a huge old log where I daily walk the dogs. I could pretty much disappear in it (although I am not going to try). Very nice work in your yard!!
