In this second NSFG Extra from the Civic I/O mayors summit at SXSW, J.B. Wogan speaks with long serving US Conference of Mayors Executive Director Tom Cochran, who sketches out a through line from civic innovation to civil rights and back.  The governing crew - J.B., David Kidd, and Dustin Haisler - also take to the patio to compare notes on what we learned during day one of the mayor's summit.
