From Thinkwalks:
Before bikes were invented, the popular Wiggle bike route was a foot trail to avoid these same hills. Change the way you see the landscape as we talk about everything from art and bike politics to floods, lakes and native societies. We’ll discuss the very latest research on how the Mission Dolores was, it seems, founded in the Wiggle. Later, the city expanded to fill the valley with houses, but why? And what was there first? It’ll be a quintessential mix of Thinkwalks themes on a flat one mile walk (each way).
