The church can find folks to whom they can witness at Public Events of all types.
Soul Winning can be learned and exercised at public gatherings.  

Public Events offer a wide variety
The community goes to Fairs, Festivals, Markets, and Parades to which a witness can be exercised.

Fairs and Festivals offer more opportunities for witnessing than any other venue in a community.

About 1/3 to 1/2 the population of the United States attend public events. How else could Paul declare that he was “pure from the blood from all men” if he had not worked in the public market places of his day?  To be pure from all and declare to all, we must contact all of our community and communities around us.
