As you are not in or from Iceland I think I must explain my saturday pictures: Hveragerði is a place abput half an hour from Reykjavík. There is lots of thermal heat under it and in glasshouses they grow flowers and tomatoes and some bananas for the tourists. Behind the house where a freind of mine lives there is a very nice little river and the steam you see is one on many outlets for bundeled energie from mother earth, tamed to heat human houses and glasshouses. So here they blow the steam off and together with the water and frost it makes qiute an interesting view. It is just there - no fence, no nothing around it.
