Refreshing transportation news, readers! San Francisco is set to get water taxi service. The San Francisco Port Commission just approved a five-year agreement with John Scannell, who runs those duck boats for tourists via Bay Quackers, "and plans to launch the taxi service within the next two to three months." Service will depart from Pier 1½ or the Hyde Street Pier. "A one-way fare from San Francisco to Oakland will cost about $18." [Mercury News]
