That's great...
My ex-father in law, tells one about his crippled old dad graping a wire he Thought was dead.
The old fellas cane wound up in a tree, while his wood leg wound up on the other side of the fence.
To this day they all think he swallowed his dentures because they were never found.
I have the same 25 mile box for my dogs, and a 50x50 yard... Yes they do frigin hurt.
