So, here in the Netherlands we have a very big DIR-community.
There are several parts to train, knows as the Beldert and Vinkenveen. Both for lake dives, and of course some wreckdiving at the Northsea.
Every year DIR-NL organises a meeting for all members. Also people from DIR-BE (Belgium) and DIR-GE (Gemany) will be there.
For the cave-divers among us, we go to France (also for courses) and some mine dives in Germany.
