This garden was an early example, with raised beds, solar panels and a compost-heated greenhouse, a hidden bioswale and more in Open Road's student-designed garden. Students won a patent for a unique composting bin then and now:
"As a high-school student, Environmental Program Coordinator, Nando Rodriguez designed a unique composting bin. This original design is currently used by members to build bins for our garden. Over the course of the year members collect organic material from our headquarters, local residents and the garden itself, and engage in experiments with various composting techniques.
