The Book Forest in Berlin

I love these places little book lend boxes. My home town has a exchange box if you take a book you have to leave a book. I once found in it a signed book. I sent it to my dad. It was Stephen King Dolores Claiborne, my Dad went crazy over it. In return I left 2 books I had laying around I don't remember what I left.

There was a thing that went around my neighborhood called the bookmobile that operated kinda like an ice cream truck but you could take books instead
