They WILL go door to door. Instead of an ignorable phone ring during dinner hour, there will be parades of former telemarketers ringing the doorbell. And SCOTUS recently ruled that door-to-door pitches are pretty much unstoppable.

How about a sign that says "NO SOLICITORS TRESPASSERS WILL BE SHOT", beside a laminated used pistol target... the use being the object of a couple of loads of the buckshot of your choice from about 7 yards. Seriously I can't believe that the SCOTUS would rule that you must allow folks onto your property that you don't want there. Apartment dwellers may have a problem though, unless the entire building or complex is declared off limits to uninvited salesmen, since the common/public area pretty well extends right to your door. Do you have a link to the decision, or at least the name of the case?

Now That is creating a 'hostile workplace' for door-to-door salesmen!
