Protecting Power Cord from Theft

I have a portable surge guard and I was concerned that someone might take it. I bought a steel ring about 2 inches in diameter and 2 feet of chain. I split the ring (hacksaw) and put it around the cord of the surge guard and slipped a link of the chain on the ring also. I then spot welded the ring. I wrap the chain around the pedestal and lock it. I also put a ring around my 50 amp cord and can slip the chain from the surge guard through it before locking all to the pedestal. This stops the casual thief but bolt cutters will still get it in seconds. I did all this when I first started camping but have never lost anything in 20 years so most times I don't even bother to lock things.
