With my heroic civ I just got CB from popping a hut by planting a city right next to it. My Musical civ I just discovered IW and I have one source just to the outside of Christine and I see that there is an iron source right next to Lyon.
There is some bad news with my Musical siv because a Barb warrior is about to near my captial, which is undefended, so instead of building a settler in a few turns I am now building a warrior, which will provide defence for the next turn.
