Boggy grounds around Gardno and Lebsko lakes are rich in deposits of the peat which, after extraction and drying up, was used as perfect fuel material in winter. Extraction of the peat was always begun in the first half of May, because the groundwater level was the lowest at that time and local fishermen had a pause in fishing. As the peat lay very superficially under the surface of the ground, the technique of its extraction was very simple. After the burn up of the grass, one cut down outer patch of grass with the hoe and with the special knife on a long handle one cut layers of the peat, forming it into cubes of similar sizes by means of the special tool of blades at right angle.

There is a forgotten tradition that is somehow being reminded by the plain-air picnic called "Black Wedding". It is organized in The Museum of the Slovinian Village in Kluki every year. This year's ethnographic performance, which took place traditionally on 1÷3 of May, was delighted with the big interest of the local population and tourists who appeared in Skansen museum, coming together with all families from far-away places of Pomerania and Poland. As every year organizers did everything so that the visitors and guests could spend a few unusual hours among centennial, rural crofts.
