What is the differences between Norther and Eastern Garters? Are there any? I've tried to search this out on the web but I can't seem to find any answers. There's a on-line place called Backwater Reptiles that has Northern hatchlings for sale and I'm debating on ordering one. I e-mailed to find out if the are w/c or c/b, I really don't want a w/c due to health issues. Any input would be appreciated.
