Secrets of Glen Canyon: Dynamite, bears and a freeway revolt

Glen Canyon is one of the most underrated parks in San Francisco, with a dramatic history that's mostly unknown beyond the Glen Park neighborhood. Glen Park Neighborhood History Project founder Evelyn Rose joins Total SF hosts Peter Hartlaub and Heather Knight to talk about the canyon's history, including the dynamite factory (and a huge explosion), the zoo and plans for a freeway that were successfully fought by three women called the "Gumtree Girls." Also in this episode, Hartlaub and Knight get another called on the Total SF Party Line (415-777-7413), this time asking about Heather's open dislike for "Star Trek" movies. Produced by Peter Hartlaub. Music from the Sunset Shipwrecks off their album "Community," Castro Theatre organist David Hegarty and cable car bell-ringing by 8-time champion Byron Cobb.
