People who know each other from the street and operate under the name Streetlight usually go to Princeton and Rutgers (on the street near the Universities), or sometimes New Hope or Doylestown, PA. Some go to the NJ boardwalk in season as well, and have shared information on campuses on rare occasion after getting permission via someone who is a Christian and a student.
Streetlight Info operates via streetlightinfo.com and is separate. Both Streetlight and Streetlight Info are made up of independent people and neither are official organizations.
