When a Sierra Club leader accepted the last person waitlisted for a Chaco Canyon service trip in 1988, Susan Estes participated in her first service trip to the Four Corners. Since then, her service trip odyssey has drawn her to Utah, Colorado, Arizona, New Mexico, west Texas, and, following a close scrutiny of the globe, to Hawaii (which is, in fact, "southwest" too). Enduring friendships, a wicked sense of humor, and the high energy of a committed group doing selfless service top the list of reasons Susan does service trips. And, yes, she still makes a special effort on behalf of any of her waitlisted participants.
