When we bought our farm property I put surplus concertina wire around the perimeter of the woods and up the drive. Then we planted blackberry canes all along the rows and they quickly covered the wire. The deer just jump right over it but it keeps all my neighbors dogs off the property. My newest addition has been to install a heavy steel gate with an electric remote that's 12V with a solar panel recharger.
The best part is that the house isn't visible anywhere from the road but from the house and my shop I can see all the property lines by looking out the windows downhill. I also keep a few Galil's in 308 up where they will be useful.
Honestly I don't think it's rioters I need to fear. But better safe than sorry.
Be sure to check your claymores periodically as their positioning may shift with time and the connectors may corrode :)
