Joe Greenwald, Inc. 
Lingle, Wyoming 

Bryan Greenwald and his sons Rhett and Barry discuss their operation in southeastern Wyoming, with emphasis on the critical role that water plays in our agricultural systems. The Greenwalds have adopted sub-surface drip irrigation in an irregularly shaped field that would otherwise be challenging to irrigate, increasing both conservation of water and labor. Their cropland also is home to a historical monument - the location of the Grattan massacre.
