I had never known petangue is such an interesting game. Everybody should try it :)
I took this picture at 2 am at one of Prague's island where we go to play. Usually after midnight, ending like at 3 am or so. The island is called Slovansky island but everybody knows it as Zofin (named after the mother of Franz Joseph I). It is in Vltava river very close to National theatre. There's a weir nearby, too. You can smell the water here. Only the salt is missing and it would be like at a sea :)
