I don't get the lingonberry thing. Locally, they are called cranberries or low-bush cranberries. Folks will put a lot of effort into picking blueberries, but not so much into cranberries.
You can put in a busy hour of stoop labor and only have a couple quarts to show for your effort and even then, they are just cranberries ; -)
I bet if they grew in your backyard, you wouldn't think they were such a delicacy. They are better than no berries at all, but that's about it.
