At this point / I would like to quickly / say something about the source And specifically to quote the incomparable humorist Heinz Erhardt (1909 - 1979), who was known to a wide audience for his wit and "Another poem", with a short four-line line: "There is certainly a lot of beauty in the element, the wet. Because you can drink the water. But you can also - not." (H.Erhardt)

In Lucelle you have the possibility to get supplies at the gas station. I didn't see anything to stop by. But I wasn't looking for it either. At the lake there are benches in the sun and in the shade. The fauna on the lake was rather sparse. The small stream with the tiny waterfall is quite picturesque. But the place is nice for a short rest and pause.
