[old car guy]

I was having a problem living in the center of the city with un welcome people just walking around in my yard and going around the back where my shop is. I put some beware of dog signs up and went to the pet store and bought the biggest dog collar they had. I got about a 8 ft piece of a logging chain and attached it to the collar. Put a short 3 ft piece of 2 inch pipe down and welded the chain to it. Placed it up on the open side of my driveway the unwelcome traffic has completely stopped. Infact the electric meter reader was so concerned for the first few months they just estimated the electric meter. He would not come past the front of the house. Try it it works, who would entry to walk back when a huge dog had trown his collar and is loose.i do move it around time to time so it's never in the same place for long.
