The stack of cards grows...

I just checked the PADI Pros website and my Master Scuba Diver Trainer cert has gone through and I should be getting another card in the mail. I realized that I've accumulated a stack of certification cards in my 9 years(to the day!!) of diving. Wow, today is the 9 year mark! Wahoo!! Well, in the picture below is all the certification cards that I've got. The mouse is for size reference. More than half of the stack are current, meaning I've gotten in the past 6 months! Holy smokes!!
