Thank you Chris, positive thoughts are always welcome!

We don't know if the snake left. If it did, it left by means of some exit that we missed in inspecting the foundation.
We've decided we're lucky it's nonpoisonous and nonaggressive.
I wondered when my Dh will finally get curious enough to go back under the house and see if the snake's still there?

So ends the saga. lol
