I don't know if they can interbreed or not Nyboy. I would imagine it would be very dangerous for the rat snake. A King Snake can, and will, kill and eat other snakes. I'm certain that this was a Black Rat snake. Like I said, I could see the remains of it's juvenile pattern. I don't how many times I've been told by people that they just killed a Copperhead, only to find that all they did was rid the world of a young Rat Snake.
Anyway, update time:
Yesterday I pulled the carpet from under the living room window on one side of the home. The damage was worse than I anticipated, and led to me having to finish taking out the remaining lower cabinet and existing bar. I replaced about 14 linear feet of floor along that wall, so that side is done. Now I only have one bad spot left, under the window on the opposite side of the living room. I was going to tackle that today, but that meant moving the rolls of carpet and linoleum along with everything else piled in the way. I have been worried about the lino rolls flattening out because there are no tubes in them. So, instead of moving them, I finished prepping the guest bathroom floor today and put the linoleum down in there, and out into the hallway. After all, we have a new bathtub coming any day now and the only place to store it is where it's going to be permanently. I think Dew may have got a pic or two. It looks really nice.
I then moved into the master bath and took the toilet out. I may have to replace the floor surrounding the toilet drain, but before I could make a decision, a storm moved in. It was too dark to work inside and I'm not subjecting my new generator to a direct downpour, so we called it quits for today.
In other news, I had a friend who is also an electrical contractor come over last night and take a look at the service entrance. It's URD, which isn't technically allowed in mobile homes anymore. The reason is kind of dumb. URD doesn't have a flame retardent jacket, so if exposed to flame, it will burn. I'm sorry, but if the service entrance cable is being
exposed to flame, in a mobile home, you have much worse problems than if the wire jacket will burn.
Anyway, my friend called his friend the electrical inspector. The inspector said he would let it go, because he thinks it's a dumb code too. The cable is in conduit all the way from start to finish, and buried 24" underground. It's unlikely to come into contact with flame

So, that saved me about $1000 in a new service installation. Thank God above for the little things he does to make our lives just a bit better.
Tomorrow, I would like to get the other side of the living room done, and also the area around that toilet if I decide it needs it. Frankly, I'm leaning towards just doing it and getting it over with.
I'm hoping to get the laminate down in the kitchen by the end of the week too. I still have to get the poly finish on the rest of the upper cabinets so I can hang them and get them out of my wood shop so I can move the lowers in to finish them.
