uh, they don’t need to step on your property. If they can’t see the smoke from the street, a quick flyover with infra red photos would do the trick.

True. And, when caught, I plan to tell them it was smoke from a group medical marijuana therapy session, attended by an all-gay crowd, during which we planned disruptions to local Catholic Masses for being anti-Obama and anti-abortion.
