December 7/10  Went to see the new bridge over the Hoover Dam  We walked over the bridge called the Mike O'Callaghan/Pat Tillman Memorial Bridge. Pat Tillman was killed in Afganistan in 2002.  Mike O"Callaghan was the design engineer of the bridge.  It is 1920 feet long and 975 Ft above the water.  We walked from Nevada to Arizona on the sidewalk.  Spectacular!!!
