Drain the Oceans on the National Geographic Channel is one of my fav shows to watch. It's cool how they research info to find out how and why these ships ended up in the bottom of the ocean. This episode was particularly of interest to me because it is about Rum Runners and the Mob during prohibition and some of it talks about the booze going to the US from Canada and takes place in Southern Ontario where I grew up.
