Fuck all this....

Get yourself some poison oak, ivy and sumac.

Get that shit all ever their cars, door knobs, seats, etc.....

Hell take them a gift basket full of some herb and have some dried poison oak in it.

In 7 days their lives will be holy hell and for the next 3 weeks, they will endure the lesson to never, never ever ever fuck with your plants again.

With any luck, they'll be allergic and never bother you or your shit again,

Trust me it will teach them a lesson and give you a bit of revenge served cold.

To turn the other cheek, will certainly guarantee a repeat performance if you grow again. Everytime. Theives are like that. They dip from the same well twice.

Count on it.
