Hey Mike, I wish I could help, but I don't know of anyone in the U.S. who is keeping them. Platyceps seems like a very interesting genus to keep though. You might try posting / asking on the racer and coachwhip forum. I would probably watch the classifieds for imports - maybe someone in Europe is breeding some... Best of luck, and please let me know if you find some to work with, as I am a fan or racers and rat-racers too...
