Kidding? In today's world of counterfeit watches and identity theft, do you really think that coming up with a shiny new dive card is anything harder than finding someone with a good scanner and a sublimation dye printer? I have actually seen one at Blue Spring, in Orange City Florida for a cave diver that I KNOW to be fake. The guy was kidding about it with his homies. When I brought this up to the front gate, they told me that they were not in the business of checking out certification agencies. If you have ANY card, you can go dive! Go figure.
