Giving up my indigos when I lived in Maryland to move down to Florida was definitely one of the drawbacks of that decision. I loved the hell out of those guys. Probably one of my fondest memories was when my first clutch hatched out on my birthday one year. I stood there with a double handful of beautiful baby eastern indigo snakes and just stared at them.
Heck, it's breeding season right now for those guys, isn't it?
Sure would be a crime for someone to actually breed a species that is being protected because of habitat destruction causing their decline. So the only way you can have one is if you take it OUT of the gene pool by keeping it a captive, separated from other breeing capable adults ...... Duh.....
