reply to dingdongditch Think outside the box. Go full tilt cartoon on the kids. Break out the Acme catalog and buy an anvil to hang over the front door. Maybe a Spy vs Spy approach with a trapdoor and pit of sharks/alligators/pirranah. A couple pounds of flash powder if TNT is out of stock. I bet a few million lumens would make an impression. Get creative and make it memorable.
