They are very popular. There are lots of Kluby Morsów in Poland. I don't belong to one but saw them in action many times :)
There is also one (or two) school walrus club in Poland.
Press never cease to be amazed by them and because of that every winter they enjoy extensive press coverage.
Years ago I stumbled across a newspaper from the beginning of 80s. There was an article about Morsy. The only difference was that they were completly naked. Hardcores :D
