The Crosstown Trail is the hike San Francisco needs right now, traversing the city on a 17-mile diagonal and daring the walker or biker to fall in love with the city again. Hosts Peter Hartlaub and Heather Knight interview one of the Crosstown Trail's chief advocates and creators, Bob Siegel. But first Hartlaub and Knight recap the 30-Day Small Business Challenge that just ended, and announce their new Total SF Book Club title.

Produced by Peter Hartlaub. Music is "The Tide Will Rise" by the Sunset Shipwrecks off their album "Community" and cable car bell-ringing by 8-time champion Byron Cobb.
