Some people are so closely twined with the major events of one's adult life that it's hard to imagine a wold without them. Tom Hayden was surely one of those people. I never knew him and only heard him speak in person a couple of times. Those instances were inspirational and informative, filled with the kind of wisdom that citizens of this country need to hear again and again. I will always remember him standing in a shaft of sunlight in the Capitol Rotunda, here in Madison in 2011, as we added our voices to the still-ongoing noontime protest with the Solidarity Sing Along. Hayden's obituary can be found here.
