Wow, 10 months and no replies to a cool question!
Where to start?
The weather. Hot summers (but short!) by the lakes, and hard cold long winters, noting like -20 to get the blood pumping :)
The fishing. Good pike fishing, and Zander too, it all tastes good.
The food. Its not just meatballs and raw fish, Sweden has a long history of great cuisine.
The hunting. Elk, wild bore and roe dear, all tasting lovely.
The culture. Its a country where they are proud to fly the National and regional flags, and most people do.
The people. Under a tough exterior are a warm and friendly people, with great family values and open and a warm welcom.
Just a few of my favourites, I love it there to be honest, and EVERYONE should go there at least one to try it!
