Where did it come from?
We do not not have them this far north.
Weird!
I once saw a water moccasin swimming up a run in Arlington- at least that’s what everyone who saw it thought it was, and it certainly was pretty big- but unlike Buffalo I wasn’t inclined to grab it for a closer look.
Salamander,
The snake came through the plumbing from the septic system.
Like I said. It was a rural area. We had well water and a septic tank with leach field pipes. It had to come though there, because the toilet seat was down and there was no other way in.
