Cache In Trash Out (often abbreviated to CITO) is an ongoing environmental initiative created by Groundspeak Inc. related to Geocaching which encourages Geocachers to clean up areas parks and other areas. This is done in two ways: specific events, traditionally around the time of Earth Day each year, in which groups go around picking up litter and maintaining the landscape and collecting litter whilst finding geocaches.
