Jim explains

Can I leave my card?
"No, did I mention that you are on private property?"
What do you mean?
"This is private property, you weren't invited, so you're traspassing"
Huh?
"Do you have a village solicitation permit?"
Huh?
"Did you see the sign on the edge of town that says permit required for
solicitation?"

I do that to the Witnesses & the Mormons. I ask if they were invited
to the complex by a homeowner. Of course they always answer NO. Then
I inform them of the trespassing laws and as soon as I close the door
I'm calling the cops.

I guess my address is now on their "Do No Call" list. The Witnesses
were here yesterday but no one came to my door.
