Yea, the poison route is effective, but you can have catastrophic results!
My poison was green, and when I started finding little green turds I knew the poison had been ingested. Most of the time they seem to crawl away, but not this one. The smell of summer cooked dead flesh was just the worse smell possible. I couldn't drive the wagon for 2 months last summer.
And, I never found the carcass. I've had the seats out and even the dash, but no body.
Fine now, though.......
