From Shaping SF:
This trip through San Francisco's lost sand dunes, ponds, creeks and coastline will focus on the city from the center southward, covering the Mission before heading all the way to Candlestick Point and then making our way northward along the bayshore. Candlestick Point State Recreation Area, Heron's Head Park, The Farm, community gardens, San Bruno Mountain, and more! It's a social, historical and critical tour through the city's ecological past and present.
