Drive Dubois to the boat house. An intermission sequence showing Dubois dying and you escaping Jericho will appear. You will be trapped in a room while they blowtorch a door to get to you. The best way to get out is to get on the forklift and
lift up one of the green boxes. Drive slowly in between the broken uprise against the wall. Then, climb up the ladder to the uprise. They will probably be shooting at you by this time. Jump from the uprise to the box, then to the other side. Run down that side to the ladder. Get the gun in front of the ladder. Climb down and collect the health at the bottom. Shoot the man in the boat outside of the boathouse. Then, jump in a boat and back out. However, beware of a man in another boat shooting at you with an Uzi. It is possible to get away in the boat without killing him, but if you feel the need, shoot him. Then, drive to the river you came down before getting caught with Dubois. There will be two boats with two people in each ready for you at the mouth of the river. Drive close enough so that you can shoot them, but they cannot shoot you. After killing them, drive the boat up the river. Get off the boat and go up a ramp. Get in a car without the "red" drivers on your radar seeing you; if they catch you it is difficult to kill or escape from them. Drive to the destination. Enter the "circle road" on the west side then take the first right. Drive until you see a road that goes up a hill on your right with some white stones blocking your car. Get out of your car and go up the hill. Calita's gang have set up a road block at the top of the hill. Shoot them. Then, to get by the cars (you cannot get in or jump over them), shoot the grill of the car facing you until it explodes. You should have plenty of ammunition if you picked up the gun at the boathouse. Then, walk until you see another road that goes up a hill on your right. Walk up that hill and turn right at the top. Walk until you see a street that goes up a hill on your left. There will be another roadblock waiting for you. Shoot them. Blow up one of those cars so that you can get by. Shoot the two men that are standing in there. Then, run to the arrow. Someone will be shooting at you. However if you get to the arrow you do not have to worry about them.
