Yes, many Norwegians - those in convenient locations - make largescale treks to Sweden to buy food. Crazy stuff.
I spent much of the summer in Stockholm this year. Weird thing going on there --babies. Lots of 'em. (and not the muslims, the ethnic Swedes). They are having four kids a piece. Kids were every where. It was a marked increase from when I left just three years ago.
I am really curious how this will change the priorities of the average Swedish family. It's one thing to pay for everyone else when it's just you. Quite another when you have six mouths to feed and clothe.
