I used to work in R&D for a seed company. One time they had us grow a plot of castor beans. Apparently ricin is used in some medicines and they wanted to see how much they could produce per acre. We didn't know exactly what the plants looked like and we planted them next to a county road. Turned out that they look very much like pot. Several people driving by reported us to the sheriff so we had the cops out to see what we were up to.
