Pablo, I met your father in the late 60's when he was still very active in the Sierra Club's West Los Angeles group. He helped me get motivated to go outdoors and appreciate nature. I joined the club and in '74 climbed Moses Mt as a BMTC training backpack. I don't know if Fred went to Moses Mt but I like to think part of your father's legacy was with me and with many other hikers and climbers that he inspired for many years.
