What do you mean by open bay? When I was there we had three different types of accomodation. Large tents with coal burning stoves, low squat buildings with coal burning stoves, and once we actually stayed in real barracks up on the main post area.
In the back area there were barracks that held something like 18 or 20 people in a single room. They must have been extended stay quarters. We spent about 7 months at a stretch there. After two(2) years my time was up and came back to the states.
