Hmm, the babies do look similar, though nowhere near to having that much red. I'll have to see if I can get a better picture of one later that shows the color more accurately.
Does anyone have any links or images of an anerythristic red-spotted garter? I tried looking for some last night, but I can't even find reference to such a thing.
It does make an odd bit of sense, since I am in Oregon. Perhaps the kid had lied about where he got the snake fearing I'd make him let it go (he was keeping it in a dark, locking crate in about an inch of dirty water. It had been kept that way at least three days). But, this girl didn't act like any wild caught I'd ever encountered. She took to food right away, and will eat dead fish. She seems to solicit my attention, coming up to the glass whenever she can see me. If I walk to the other side of the tank, she follows. She doesn't do that with anyone else in the house.
She really does act tame and well handled. So, I'm just awful confused now. Lol.
Many hours were spent trying to ID her, and an eastern true blue was the best anyone could come up with.
Now I'm left pondering whether or not I should let them all go. But, if the female is that rare of a sight that no one else has or knows of such a thing, maybe it would be better to keep them. It could potentially help a breeder in the future to produce such a line of blue beauties with success. This snake is really winning the hearts of the people living around here, even my neighbor who hates snakes got all doe-eyed and wants to buy a baby. 
Ahh, I babble and have grown attached.
