Fun fact; the border follows a river. In some places you could just walk across.
At least in the winter time when the river is frozen. Otherwise, you have to swim.
Just a little question, what is up with Finland and Sweden? it seems like they are best friends or something cause I haven't seen anything about Norway or Denmark and they are a lot closer with languages.
Finland once was a part of Sweden and there is a Swedish speaking minority in Finland.
Doesn't mean we're friends tho... :D
