i was wondering that there was in netherland a tourney badminton in the month august at the side of belgium but still in holland
Check the NBB tournament calender at www.badminton.nl for all august tournaments. Any tournaments in june just over the border in Belgium?
I would also suggest this site: http://www.toernooi.nl here you can view badminton tournaments that are mostly played in Netherland. its worth to take a look
