There should be a gray building in front of you at the forth gate. Enter the open door. And as soon as you go in, turn right and go up the stairs. Go slowly, and when you get to the top, you will be in a hallway. Keep going until you see more stairs. Go up them very slowly. At the top, go straight to get to the lookout tower. Go slow and do not fall. Go though two doorways. Keep going straight, then go up one more staircase. You will now be up in the lookout tower. Remeber, go slow as you can fall easily up there. If you fall, you will have to start all over.
FLY Around Fort Roberts:
First, you must find the airport, look for the helicopter (it will land in some rundown buildings around the airport) but when it gets close to the ground, pop a wheelie and hit the helicopter with your front tires. If you do it right, the helicopter will pick you up and you will fly around with it until you hit reverse.
