NO, I just call them smoking pits.. The right term is DSA. No there is no unofficial areas.... I recieved 2 different maps..because we switch rooms.. on either of them did it read DSA. They were normal maps that did not list any smoking areas. You just saw them posted. Most of them are in the sun. Only 2 I remember being in the shade is backside of the main hall; before the walk down the stairs to the main pool. The second, by the bus stop. The ones around the lake are in the sun. The computer pool is the sun. I hit about 6 different ones.
