Hello NitroX,
Thanks for the reply.

No, not a beaver, it was a woodchuck.

He had taken up residence under one of our range buildings.
He made so many tunnels under the concrete floor that the floor cracked and collapsed.

I had been trying to get him.
Then the day I was shooting the Cape Gun, he came out.

And, he was finally dispatched,

But now, his brother has retaliated and is trying to get even with me.
