Wow -- And as far as the second day, and being on guard all the time . . . I honestly think that's one of the things everybody SHOULD get from a Rescue class. If you come out of the class with a heightened awareness of where the opportunities for problems exist, and you are watching for them and thinking about how to avoid them or deal with them if they occur, you really have learned the lesson from Rescue. It's not so much about handling specific problems, as it is a mindset that problems can occur anywhere, and divers should be thinking about how to keep them from occurring, and how to deal with them when they do.
