For almost certain, there is nelsoni/sinaloae in it. The rest will always be suspect but most likely a readily available milksnake like campbelli or hondurensis (or annulata.)

IMO, annulata are still kind of a locality favorite. Anybody can do anything of course, but I bet there is less of a chance of someone crossing annulata with anything else. Nelson x Pueblans on the other hand were done in numbers to attempt to make albino orangey milks.
