Drawbridge is a small, marshy island at the southern end of San Francisco Bay. People started going there in 1876 for the excellent hunting and fishing. By the early 20th Century, Drawbridge had become a full time community for a handful of families. It had also become something of a weekend resort.

By the 1940s, pollution in the bay and urbanization nearby had destroyed most of the island's hunting and fishing. Today, Drawbridge is a ghost town of gray, weathered buildings sinking into the bay, and is part of the San Francisco Bay National Wildlife Refuge. Huell goes back to Drawbridge with some of the original inhabitants and gets a very special tour.
