As a staff scientist with SABIC, a large petrochemical company based in Saudi Arabia, I live in a compound for western expatriates in the outskirts of Riyadh. At first, the compound appears to be located in Sing-Sing. It is surrounded by tall concrete walls with barbed wire on top; there are also concrete barriers, like those you see on U.S. highways, all around it. To get to the entrance, one drives through a maze formed by the same barriers.
