Actually redvip, in the old days the WTBS was much more open to using different methods for "spreading the word." It's just in the last 50 or so years they eliminated those avenues and focused solely on the door to door. They did run some PSA's and also took out some full page ads in some newpapers not so long ago. Can't imagine they had much response from it.
I just wonder how they sugar coat their doctrines to the interested. That is why it would be great to have a kiosk nearby with handouts or a place one could put flyers outlining bullet points of those crazy doctrines of "jw.org." A cartoon titled "The jw.org bedroom" with the red "no" circle placed over positions. A cartoon of a child needing a blood transfusion with the red "no" circle over the blood. Children begging to see their parents, and the "no" sign. Something that makes it reallys simply and clear what they really believe besides "wouldn't you like to live in a world without war and sickness...and have a pet lion?"
