That only works in some circumstances... I keep this place looking empty from the front. No vehicle in the driveway, yard a little overgrown. I've surprised 3 that thought it would be an easy place to rip the copper out of. ;)

I keep Casa Pachysandra looking occupied all the time. I even got my neighbors, who have 5 vehicles, to always park one in my driveway. Computer room lit dimly, with the monitors tuned to Steel Guitar Radio.
You could have given your esteemed guests a few pieces of copper at several hundred feet per second, just to be sociable.
Didn't realize fertilizer prices were that high.
