On Friday, November 29, 2019, Friends of Princeton Open Space (FOPOS), a nonprofit devoted to preservation and stewardship of land in Princeton, will host their annual OptOutside event at the Mountain Lakes House in the Billy Johnson Mountain Lakes Nature Preserve, 57 Mountain Avenue, Princeton.


#OptOutside is a movement to encourage people to spend time in nature rather than in crowded stores Black Friday shopping the day after Thanksgiving. The community is invited to the Mountain Lakes House to enjoy a nature-themed art activity, music, cider and snacks from 2:00PM to 4:00PM. Trail maps will be available for walks and hikes before or after the event. All ages are welcome to this free, rain or shine event. While the event is free, attendees are requested to pre-register via (search “OptOutside in Princeton”), to help FOPOS plan for attendance numbers. 


November 29 is also the kick-off to the FOPOS Give Thanks for Nature Photo Contest.
