wendy,
The Witnesses set up a table in one of our local malls advertising the WT publications as well as the books and pamphlets. On occasions my wife and I will sit across from the table and have a cup of coffee when we have a few minutes to kill. (This was a few years ago)
I have several people that were never Witnesses ask for the free literature that was put out. The witnesses got wise as to what was transpiring, and two years ago started taking the names and address of the interested party so the Witness could drop off the literature at their home and try to get a foot in the door to do a little preaching.
In all the time the table was set up at the mall and people could receive the literature right there, I obtained over 700 books and over 1500 magazines in three years.
The Witnesses think they have the problem licked.
