As am mp we had to check every door on every igloo once when we came on shift. You had to sit on the back of a trucks tailgate and the other mp would drive in and out of each pad where the igloos sat. You had to jump off lean over the giant "King Tut" concrete block in front of the door and give that big cylindrical pad lock under the rubber weather flap a jerk. Up one street and down the next till you did all of them in the Q. Boring but had to be done. There was no anti satellite steel cage in front back in those days (mid 70's) and there were considerable forest areas between the streets which were cut down later on.
