The Two Sisters document their travels to several observatories across Arizona, including the Whipple Observatory near Amado and Kitt Peak National Observatory west of Tucson.
Midge Lemay and Sue Poirier describe the scenery on their travels, the history of the observatories, the exhibits in the visitor centers, and other observatories in Southern Arizona they might add to their list of places to see.
The Kitt Peak National Observatory is on the list of the 25 best observatories to visit in the U.S., compiled by Space Tourism Guide.
