Read the paragraph from The Hot Zone. There was not a uniform in the group, although a few members of the ambulance team wore camouflage fatigues. The caravan crossed the Potomac River at Point of Rocks and hit Leesburg Pike just as rush hour began. The traffic became bumper to bumper, and the officers began to get frustrated. It took them two hours to reach the monkey house, contending the whole way with ill-tempered commuters. Finally the column turned into the office park, which by that time was filling up with workers. The supply van and the ambulance were driven along the side of the monkey house, up onto a lawn, and were parked behind the building, to get them out of sight. The back of the building presented a brick face, some narrow windows, and a glass door. The door was the insertion point. They parked the supply van up close to the door.
