We walked where they walked and viewed the ruins of a four-story building they built centuries ago now called Casa Grande.  The Hohokam Indian culture ended before Columbus sailed. Thousands of people living in these adobe villages, farming in the desert, building miles of irrigation canals leave only these crumbling buildings and many unanswered questions.  

Sherry and I visited the Casa Grande National Monument this week.  While only a one square mile preserve, it was impressive.  Today starts the 32nd bluegrass festival here in Casa Grande and we are looking forward to being part of it.
