Thanks for hosting Anders and a special thanks for featuring my frozen leaves as the banner photo.
Air - We all need air, especially this swarm of tiny flies that accompanied me on a walk along the River Bank. I sat down on a bench and took a few photos - this was an experiment.
Fire - I do not have a lot of photos of fire, and most have been shown here, so here is one of my firebugs that seem to occupy my garden in Summer.
Water - A shot of the local river Aar, just along the path where I live, with some of its numerous swans.
Earth - we had our lawn replenished with ready rolled turf some time ago. Here is the guy with a wheelbarrow loaded with earth and already growing lawn.
