If you're free this Saturday and in San Francisco - just when you thought Wood Brothers might have had enough of Hannibal - one of us is giving a talk at the San Francisco Public Library.  'On Hannibal's Trail: Biking the Alps' starts at 1030am in the Latino/Hispanic Meeting Room B of the main library on 100 Larkin Street.  Come along! Thanks to the SF Library's Jonathan and Jerry for their interest in the topic and efforts publicizing the talk with flyer drops at local bike shops, book shops and cafes!
