Hey Mitch,I used to have one quite similar.I got it at a pet store in Alexandria VA.They had imported a large female who had given birth the day before I arrived.I think there were 6 or 7 babies.Only one of them looked light.I bought the large female and they threw in light one for free.The markings on mine were darker and the background was more a greyish-white,but it did look very much the same.I allways just assumed it was anerythristic.This snake got very big,and liked road-kill squirrel.Great pictures.thanks jenni/
