New neighbors/visitors?

Here's a new neighbor. Saw him for the first time last weekend. He's an eastern king snake. Non-venomous, eats other snakes (including poisoness ones), frogs, lizards, and small mammals. Spotted him crawling up to our pond, and then following along side and finally getting under some rocks near the waterfall. He appeared to be about 6 feet long.

On a friendlier note, here's a visitor bathing in our waterfall.
