I'm with you LJ, that is creepy! Had they been from the city, a card would have been left.

Years ago a group of residents asked the HOA to post no soliciting signs at the main entry streets. It's a very common thing for HOA's to do in other areas. We were told the signs were not a "fit" for the look of the community (and yet look at the signs that grow here daily). The only thing the HOA will do is send out a community email if a resident let's them know about unscrupulous door to door vendors.

You can ask the person at the door if they have a SoJo license to conduct business in the city. If not, let the city know. Sadly, they won't do much either.
