Planning a trip to Key West, Dry Tortugas in late March or early April. Being this is a no discharge zone, and I do not have a gray water holding tank, how do you deal with this. Is it legal to discharge gray water. If not how do people deal with such things as washing the body, washing dishes etc. Do you just wait till after dark and no one is watching. I do not want to do any damage to the environment, or break the law, but I can't imagine spending several days with basically no usage of water, other than drinkiing it. Ideas, suggestions, experience.
