Hi, I'm not really a coaster freak, but I live just 100 km from the park and bin there a several times. The news about Junker come to me yesterday, and I think it's great!! Some one asked about the name and I think I got the answer. I think this is what you looking for:

A Junker or Junkkari (in finish) is some how related to that area in Finland. A Junker is what I like to call a "Härmä man" it's a man in a hat whit a "Salmiak" pathern on the shirt and a knife in the belt. It's kind of a symbol for that area. You can see the symbol in company logos from the area, like the agriculture machine company Junkkari, that has a factory in the area. Hopefully this helps.
