I had the great good fortune some years ago, when on one of my “learning about water” escapades, this one a visit to the Sacramento-San Joaquin Delta, to have been introduced to Phil Isenberg. Phil – former mayor of Sacramento, and member of the California legislature – devoted much of his life to the pursuit of solving environmental challenges. We stayed in touch over the years (this active blog is a great vehicle for such things), and I learned a great deal from him about the challenge of solving environmental problems in a world of real-world governance constraints.
