I cruise Craigslist looking for things as well. I cant believe the conditions people have their snake/animals in. It makes me want to rescue them all, but that is just not possible.
Recently I saw one guy selling a BP and in the picture the snake was climbing through the wire heat lamp fixture. Another guy was selling a Boa Python that was 7 1/2 feet long and yet another guy had a large regular style heat lamp fixture handing inside what appeared to be a long shallow tank sitting about 1 or 2 off the tank floor with a corn snake laying around it. And you will loose count of all the people that just have the snake in a glass tank with a bowl of water and no heat or hide. What is wrong with people?
I got all three of my current snakes off there. I really scored some good deals.
