March 12-14

Monday I checked off a bucket list item when we toured Biosphere 2. A fascinating place that continues to contribute to the study of environmental science.http://biosphere2.org/visit/what-is-biosphere-2
We started Tuesday with a 20 mile bike ride on the southeast portion of the Julien Wash and Harrison Greenways sections of the Loop. Beautiful views of the surrounding mountains while peddling through prickly pear, ocotillo and suguaro catus as well as creasote bushes. Then on to the Titan Missile Museum which was interesting. We'd hope to take a tour but didn't want to wait 90+ minutes.☹️ http://www.titanmissilemuseum.org/
Next we visited the Asarco Mineral Discovery Center. Interesting with a bit of propaganda thrown in. Missed the tour into the open pit copper mine.🙁 http://www.asarco.com/about-us/our-locations/as…
Enjoyed an early dinner at Casino Del Sol and managed to parlay my $10 credit, for joining their players club, into $16.50😄
We ran into Rick and Sharon, who we know from our annual trips to Lake Simtustus in central Oregon, while heading back to the car...small world. Saw a big dust devil or mini tornado en route to the rv park. Interesting fact interstate 19 is the only U.S. highway using metrics. www.atlasobscura.com/places/i19-americas-only-m…
Wednesday we drove the Sky Island Scenic Byway to Mt Lemmon. With a 6000 ft elevation gain, that's equivalent to traveling from Mexico to Canada in 27 miles, we saw a variety of landscapes all beautiful in their own way. https://www.go-arizona.com/Sky-Island-Scenic-By…
Have driven by the Air Force boneyard several times during our stay. Next time we're in Tucson we'll take a tour. http://www.airplaneboneyards.com/davis-monthan-…Read more
