St. Paul Street Evangelization (or SPSE, see link for more information) is a grass-roots apostolate which started in the Detroit area and has chapters both national and international. It involves a non-confrontational means of taking the Catholic faith "to the streets," in which trained lay persons set up in high foot-traffic areas with a ministry of presence that engages with interested persons via listening, dialogue, answering questions, prayer, and the distribution of materials (rosaries, miraculous medals, literature, etc.). 

There is a fledgling SPSE chapter in Lexington, headed by Casey Phillips, parishioner at Mary Queen parish/Lexington (email him for info), with plans to develop SPSE chapters in other areas throughout the diocese, depending on interest.
