Dewaardde,

We just missed each other. I use to be near Lille France and would travel to the eastern part of The Netherlands.

Perhaps this Netherland website will help you? http://www.euronet.nl/users/kazil/bi-tree.html

This is the new redirect on that site. I'll leave both in case.

Voila. C'est un autre en France. Bonne chance.

This is a better site for The Netherlands
http://www.treeclimbingholland.com/

There is also a recreational climber there named Mark Jacobs with whom I took the BI Course two years ago. He would be a good person to connect with. His email is:
