President Barack Obama. Hillary Clinton. Aaron Salzberg. One of these 3 people regularly wears a pretty sick ponytail and has sat down to talk water policy with the other 2. That person is our guest this week: Aaron Salzberg is Director of the Water Institute at the University of North Carolina (UNC) at Chapel Hill.  He joins host Jay Famiglietti to chronicle his journey from car mechanic to heavy-hitting water diplomat in the State Department, to his new gig at UNC. Aaron tells some riveting behind-the-scenes stories on his time working with politicians, and he and Jay start an impromptu therapy session on the struggles of working in the water world.
