A trip leader is a person who is responsible for organizing and leading a group of people on a trip. They are in charge of making sure that the group is safe and that everyone is having a good time. The term 'trip leader' can be broken down into two words: FIELD and EGO. FIELD refers to the outdoor environment in which the trip leader will be guiding the group, while EGO refers to the confidence and leadership skills necessary to lead a successful trip.
