Sweden is about the size of California with 1/4 of the population.
The notion that we stay inside during half of the year is funny. Normally foreign media loves to write about children sleeping outside in the winter and all-weather forest kindergartens. And then we have all the german tourists that love camping and hiking.
I understand that it seems strange to hike on other peoples property. It's not that I have to go looking for privately owned property, it's that I can't imagine ever having to keep track of land ownership when I am out hiking, camping, skiing or picking berries or mushrooms.
