Rod, I'd be careful. I wouldn't be surprised if you were contacted by the USDA. I'd be willing to bet that they are going to try to tear through emails and everything to find out if the snails had been transferred between other people. I'm just a tad disappointed that the customs actually let them through.
DP, I'm with you. They're amazing creatures, but, with how dangerous they are to the environment AND to people, there's just no way. Not to mention the fact that I wouldn't want the USDA showing up on my doorstep, lol. But, really, the chances of my children getting hurt would be just way too much. Plus, since they're illegal and not native, I'd imagine that it would take awhile to diagnose the problem, since they wouldn't be thinking that you were housing an illegal snail. *Shudders*
