When you go anywhere as a tourist it is quite common that people tell you that absolutely must do/see in this specific place. For example, if you go to Berlin, you must visit a sex museum, while in Moscow you must go and see taxidermated Lenin. So I want to make some list of 10 items or less (as in the movie) of things that you must do in Riga and Latvia (not including urinating on the Freedom monument).
