We are located in the northern Sacramento valley of California about 140 miles north of the city of Sacramento and 140 miles south of the Oregon border. We have our ten foot dome on a rural five acre parcel where we live. The location is in hilly, oak covered land surrounded by snow capped volcanoes. The winters are mild but wet (marine west coast) and the summers are hot and dry (warm Mediterranean). We grow grapes, oranges, grapefruit and berries for our use and are a retired couple originally from Davis, Ca. where we both worked at the Davis UC campus for some 33 years, one as a research associate in the area of plant biochemistry and the other as a campus library assistant.
