Prizewriter asked me to comment on the Pencak Silat thread.
The reason why Pencak Silat is rather popular in the Netherlands is for the colonial history Holland and Indonesia have share.
There is still a large Indonesian community in the Netherlands, who have still strong cultual ties with Indonesia. In every city there is likely to be found a Pencak Silat school.
Our Karate school has a friendly relation ship with a Pencak Silat school Perguruan Pencak Silat Pamor Badai
who teach a the same gym. The gave a demonstration at our 30th annerversairy in may 2004. It was a nice experience.
They had a truely acrobattical, animal like style of movement.
Their legs must be like rock because of the demanding low stances.
You must also know that there are extremly many styles of the Pencak Silat, because of the many islands Indonesia has. I was once told that almost every tribe had it's own system / style.
I can't say that Pencak Silat is as popular as karate in the USA. In the Netherland Karate is little better known, but as sais, you could find a Pencak Silat school in almost every city.
