Since 1983, Dutch beachcomber Wim Kruiswijk has collected all sorts of things in the sand — including hundreds and hundreds of messages in bottles. In a special episode co-produced with the Citizen Reporter podcast, Amsterdam-based podcaster Mark Fonseca Rendeiro visits Wim to hear about his collection and some of the pen pals he's made over the years.
