He is a Big Man on Campus (Base?) with his own vehicle. A lot of people have bicycles. He drives with the air conditioner on but it's not too good so he also drives with the windows open. He has to quickly roll them up (manually) when another vehicle goes by because of all the dust it stirs up. There are many areas he can't drive right to. They are like little compounds and he has to park outside the compound and walk in (his first housing area was like that). This is for security reasons.
