Parkour is not widely practiced in dedicated public facilities. Although efforts are being made to create places for it, many traceurs do not like the idea, as it is contradictory to parkour's values of adaptation, creativity, and freedom. Traceurs practice parkour in both rural and urban areas such as gyms, parks, playgrounds, offices, and abandoned structures. Concerns have been raised regarding trespassing, damage of property, and use of inappropriate places such as cemeteries. Many parkour organizations around the globe support the "Leave No Trace" initiative, an urban version of the outdoor conservation ethic created by the Seattle nonprofit "Parkour Visions" in 2008, promoting safety, respect for the spaces used and their other users, and sometimes includes picking up rubbish to leave areas in better condition than they were found.
