Beginning my tour of the Biosphere II complex. The temperature was perfect this day. The tour took about two hours. This place is immense being 40 acres or about 2 1/2 football fields long.
In another section where they have desert fog climate, occasionally they crack a window open on top and sometimes a bird or two get in and help themselves to inserts.
Apparently, there were two missions. I only remember the first mission where 8 people were locked inside for two years and they all came out rather skinny. They grew their own food but did not count on the fact that a cloud settled over the complex for nine months and crops failed so it limited their food intake. They lost 16% of their body weight.
Shadow shot - living quarters - the bedrooms were upstairs. They had TV, books, and occasionally they had dances. Two hooked up and got married after they left the Biosphere. Two were already married.
