I am planning a trip to Sweden next year.  Anything in particular I should know about it?
Well, I know that  it is a Scandinavian country in Northern Europe.
What are the other Scandinavian countries?  Maybe I'll visit them too!
Since is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, you might as well visit Denmark
Is the Oresund a river between the two?
Yeap :)  It would also interest you to know that Sweden is the third-largest country in the European Union by area.
