im doing a paper for my school about subculture profiles and i chose to write about parkour...i need help with a few things i was hoping i could get some feedback on. First i wanted to know if there any rituals among the parkour community, like anything that everyone has to do or something. Second i wanted to know if parkour has a specific territory where its practiced...what is needed for someone to do parkour. and third i would like to know some of the best parkour moves you guys have done and do u consider it being extreme, or if u know a person who has done something very extreme 

--THANKS
