March 7 Saturday Tucson

This morning we drove north to the Biosphere 2. Apparently, Biosphere 1 is our earth. Had I realized the location was this far north of Tucson, we could have gone here on the way into Tucson earlier. Anyway, we spent 3 hours here looking around and enjoying a tour.  The scale of this project and its applications provided  much to think about.

Back down the highway was Catalina State Park. We drove in, checked it out and, decided a hike to nowhere in the midday heat wasn't in the cards. We ended up at an RV show and then Walmart. This worked out in my favour as I had time to get a manicure.
