No longer usable cabins are ones which originally were in the system but have decayed to the point they are not usable. Each one will have a description. Some may have limited protection in an emergency. Cabins not in the system which are usable are shown as first come first serve and are listed in each region. These cabins are listed so we all can keep track of cabins that agencies abandon, which is a real threat in these economic times.
