The terrorist threat in my neighborhood was indeed high. I wrote previously about how they had set up a propane bomb in my back yard. I repaired it and armored it to prevent it from happening again.
On July 4, it happened again. They used their little hands to push the PVC joints apart and again gnawed through the gas hose. This causes all the gas to leak out while no one was there. I changed tanks and heard that hissing sound of a big gas leak, before attempting to light it.
Now I am thinking LOTS of duct tape. Or auto-aiming gattling lasers in the 5MW range.
