But I'm not the average person and my time is better spent visiting things of value, to me, in a foreign city. It doesn't make me any better of a person to visit Navy Pier, Pier 39, Pier One, Anthony's Pier Four or Piers Morgan just because a large dataset of anonymous people checked in there. And I don't need an app to tell me how great those places are. They hand these guides out at airports, hotels, free newspapers, paid newspapers and the internet. tl;dr: Gowalla wishes they got some of that Where money. I just searched for "marijuana" in Amsterdam and it returned two results. One was the Hemp Museum. You're better off asking a surly local or a fellow tourist.
