For next “best of” GrottoPod episode we return to our roots — and the San Francisco Writers Grotto’s roots — with guests Po Bronson and Ethan Watters. The Grotto co-founders joined us for GrottoPod Episode 2 to discuss the Grotto’s humble beginnings and subsequent growth, tracing a path that traverses more than two decades from a rickety Victorian home to an abandoned pet hospital, and finally, to the present-day Grotto, 100-plus members strong and a fixture of the Bay Area literary community. If you missed this stellar conversation the first time around, now’s your chance to dig into it.
