Location is northern part of Tucson Mountains. Hike up a steep slope and dig out buffelgrass in the morning, eat lunch, then in the afternoon tour an off-the-grid, solar-electric strawbale house with passive solar heating, earthen walls, composting toilets, & rainwater harvesting for all the home's water needs; built to minimize its visual impact on the stunning landscape.
