It's not like they'll be fined for violating your sign.
So you're saying I should spray them with water then?

That's why I'd like to have a municipal ban on solicitation. I mean, if they want to open a shop, pay rent and what have you, I'll come by if *I* decide to.
I should probably also have another bell specifically for "religion" resellers that gives them a reading from an assortment of religious passages I can keep prerecorded. I can even have it randomize between the Old and New testament as well as the Qur'an. Usually the folks going door-to-door fall into the domain of some specialty DIY texts (Jehovah's Witnesses and Mormons to be specific).
