......and I agree with him. Back when some of us older types were in the hobby strong, locality data meant a lot to those who really were into the various subspecies of milks. After all, locality data dictates which subspecies you have. And while it is true that there are no cut and dried lines as to when one begins and one ends, there are specific ranges for all subspecies. These often include large intergradation zones between them where animals cannot be identified to either subspecies with accuracy.
As Bob S. and I discussed a few days ago in the "HUGE Black Milksnake" thread, what people do with their snakes is their business. No one is implying that you need to do it a certain way. To each his own.
I don't personally understand why someone would artificially create an intergeneric hybrid between, let's say, a corn snake and kingsnake. In nature there are reproductive isolating mechanisms that would not naturally allow these two different genera of snakes to successfully reproduce. Of course, bring them in captivity and they behave different and then you have these "jungle corns" or whatever they're called. But again, to each his own.
I don't think Riley is trying to dictate here what everyone should do with their snakes. To date there have not been "natural" (in the wild) intergeneric hybrids between Elaphe and Lampropeltis. And the same would even go for the SinCals (Sinaloans X Cal Kings). Those two snakes' ranges don't even come close to one another. It is just something that you would not find naturally in the wild. And I guess that is the whole point. But again, to each his own.
However, as I mentioned in the thread a few days ago, I have seen some of the tropical milksnakes that have been advertised as Hondurans that you can clearly see a lot of stuarti in, both albinos and normals. There are folks working with Andean X Hondurans, and even some mention of attempts to cross Hondurans with both Black milks and even micropholis. Why? Some of these rarer subspecies are just neat by themselves. I personally think that the previously mentioned two examples would do nothing other than ruin an otherwise unique genetic line.
Keep in mind that those "locality nuts" you referred to actually know where those animals originated and can point to that on a map, and therefore using the current body of knowledge we have about the ranges of milksnake subspecies, have a pretty good idea of what it is they have. To some of us, that is better than not knowing and just having some Heinz 57 mix of whatever.
If it were a Black milk that you wanted, imagine buying babies and spending a few years raising them to adults, only to see that they have not become what you thought they were because somewhere along the line someone thought it'd be a good idea to throw some Honduran bloodline in the mix.
I realize the hobby has changed since back when locality data meant something, but it is that locale specific bloodline kept as pure as possible that means you will actually get what you paid for with no hidden surprises later on!!
