So far so good. After I affixed the drain grate to the corrugated base with a worm gear adjustable clamp, this morning the lid is still on.
I also posted a tiny zombie guard. He’ll chew up anything that tries to come up from below or break in from above. He’s not fussy about what he eats. He doesn’t sleep. He’s not scared of anything. Bad weather doesn’t bother him. He says the same thing Beetlejuice says:
“I’ll eat anything you want me to eat, I’ll swallow anything you want me to swallow; so, come on down, I’ll chew on a dog!”
