Even though I'm from one of the largest cities in the United States, I have lived in Scandinavia for nearly 30 years. Where I live, there is a very well-known and respected law that says that everyone is free to pick mushrooms and wild berries in the woods and forests. Treasure hunting for these delicacies is a delight and a national past time. Finding a special place that is rich in Chantarelle, a savoury and gourmet mushroom that is golden in color, is liken to finding a deep vein of gold that you can return to season after season and harvest large baskets full. There is even a special word that literally means "the place where wild strawberries grow" that is used to describe someone's favorite little spot. When you tell people that you have found whole baskets full of Chantarelles or have harvested several buckets full of blueberries, you leave out where to find them. These are jealously guarded secrets.
And even from an ecological viewpoint, it is also very important that everyone goes to different woods and different parts of the woods to find these fruits of the earth. If everyone were to go to the very same spot, the mushrooms and berries would perish very quickly, leaving absolutely nothing to be picked and gathered. Until a few decades ago, no one would even tell you how to find them; you would have to learn this from close friends and family, or from trial and error.
