"Please read a bit closer next time"
Yes, I will certainly try to do that. So to answer your question honestly, the freezer is really the ideal environment for those.
I don't think it would really matter what the habitat for nelsoni is in this particular case, unless you actually had one. Please don't get me wrong here,..I don't hate the snake itself, I hate the fact that someone thought it would be a bright idea to produce the snake.
In any case, nelsoni are found in areas that look similar to this photo. They inhabit areas of Guanajuato, west through Jalisco, and southward to the coastal areas of Colima. They are also found on the islands of Tres Marias in similar habitat.
You must keep in mind, this would be like me going over to the zonata(mountain king) forum and asking them what is the typical wild environment that multicincta inhabits, then tell them I want to know this because I have a zonata x corn x florida king that I want to house naturally. I wouldn't expect those guys to be real understanding about it either, and believe me, they wouldn't.
The hybrid forum is better for this type of stuff. But then again, most of them don't know diddly squat about the natural history of most snakes, or they probably wouldn't be over there in the first place.
Again, here is a photo of the type of natural habitat that nelsoni ranges in.
