Mary was born and raised in Southern California and has lived near Chino Hills State Park (CHSP) for over 30 years. She loves traveling, hiking and photography and has hiked on all 7 continents in places such as Antarctica (her favorite), Patagonia, Peru. Ecuador, Greenland, Iceland, Norway, Switzerland, Scotland, Mongolia, Nepal, New Zealand, and Kenya. Mary hikes often in the local mountains and nearly every week in CHSP. Mary has the dubious distinction of being helicoptered out of CHSP after breaking her leg while hiking. Her recommendation is to pay attention, even if the trail is flat and easy!
