So, we recently had this guy show up on our deck:
He was easily about 5 feet long:
He slithered around harmlessly for a bit and then disappeared into the grass. Fun Fact: Our house, for the first few years we had it, was not well insulated/sealed up everywhere so every now and then we'd find one of these guys slithering up the stairs or behind the couch. We never killed them or anything--my dad would put them in a pillowcase and then relocate them a few miles away.
And, of course, I had to take this opportunity and make some low-tier videos:
On our property, we see black snakes, water snakes, and garter snakes fairly often, in addition to all sorts of wildlife, due to all of the tall grass and woods we have.
