Your points are all well taken,and I will purchase DAN insurance before my upcoming trip.
5615mike: yes I have read the Tim and Christi post and although i haven't responded on that post directly I do want to take this opportunity to say that quite simply reading their experiences has forever changed the way I will dive in the future. I want to thank you both for sharing. On my last , and first, trip to coz I now realize that I took extraordinary risks that I had no idea i was taking: drinking too much in the evening, diving deep the next day and pushing an already liberal computer to its limits while diving air, and hardly drinking ANY water. It is amazing I didn't get bent. WHat an idiot I was. No more boozing when diving the next day, I'm drinking plenty of water, and will strictly dive nitrox: I have the certification I may as well use it.
Doc Vikingo: thank you for the number, I will call him in the next few days.
Again, thanks everyone for the input.
