Dad's Notes:  This future earth experiment, research center/campus recently opened the sealed air lock doors! Now open to the public for limited ‘Under the Glass’ tours. There is an outside and inside tour, also a 24” telescope is available monthly for special tours. No picnicking on the research grounds, there is a nice restaurant on site as well as the Biosphere 2 Hotel and conference room. Numerous road biker’s are on the hiway in this area.
