gun sumggling
the ferryman will have to take his wagon from mexico, where he took down the order, to the dock at blackwater. he then sits there for 5 minutes while the guns are "loaded" onto his wagon. he then takes them back to the place agreed apon by the person who ordered the weapons in mexico. he can choose any paths or routes he wants, but he must pick up the weapons up from blackwater.
drug smuggling
to smuggle drugs out of mexico he needs to meet the farmer who grew them and load them onto his wagon. then he must take them from that location, to ridgewood farm to "sell" them. again he can take any path he wants but he must bring the harvest to ridgewood to sell it.
REMEMBER THAT IF THE WAGON IS TIPPED OVER, OR IF BOTH HORSES ARE KILLED, THEN THE ENTIRE SHIPPMENT IS LOST.
