I thought I would share a few ideas and solicit others. Perimeter alarms, and trip wires. Cheap and easy to use. Cheap and readily available driveway alerts. They give off a gentile tone to a remote receiver. Generally less than 20 bucks. Shotgun trip wires, can be deployed quickly and not only alert you to an intruder they will scare the shit out of them at the same time. Weapons caches, and predeployed cover. Sheets of scrap steel can be had for a few dollars at a scrap yard. They can be prepositioned as needed, along with spare weapons an ammunition. What’s your take? CT.
