founding a booster club in Europe

I’m a passionate breakdancer, but I also feel lonely sometimes, as there’s no enough people in my area that share this kind of passion. So I was thinking of creating my own booster club to encourage people to give it a try. It is healthy, fun and very very exhausting. The only problem I have is, that I am based in central Europe and booster clubs are not a thing here. How would you best explain this concept to a culture where booster clubs are non-existent?
