I think the tract campaign would be even more successful if the following instructions were given:
Brothers, wear a long rain mac and a trilby hat pulled down over your eyes. That way nobody can identify you. Walk to the door backwards, looking left and right suspiciously as you go. Dont stand directly infront of the door in case the householder spots you through the frosted glass panel. Instead stand with your back to the wall, steal your arm round to the side and slip a tract in the letterbox quicky and quietly.
Sisters, wear a 1900's wild west saloon bar costume. Distribute your 50 tracts between your cleavage and your two garters. Compel each householder to retreive their personal tract with their teeth, but do not engage them in conversation. Tell them it is rude to talk with their mouthes full! Leave the householder with a positive thought like "Well spank me hard and call me Mary".
