TCI Membership

TCI is an organization for people who love trees and getting up into them. Members are children and adults, male and female, from all walks of life. Some of our members climb as professionals, but the majority are people who climb just for the sheer pleasure of it. Some join to meet and climb with others. Some join to learn or be challenged by new techniques. Finally, some members don't climb themselves, but they like to read about and support an activity close to their hearts.
