Red Rock Island is just a pile of rock in the middle of San Francisco Bay, over near the Richmond Bridge, but it's a privately owned pile of rock that spans three different counties and is now on the market for a cool $22 million. As the NYT/Bay Citizen reports, the place was home to sea otter hunters in the early 1800s -- hunters who drove the Bay's sea otter population to near extinction -- and a San Francisco man named David Glickman bought the almost-6-acre island in 1964 for $49,500 with big development plans. He later sold the deed it seems, and someone is now flipping it for a nice profit, having once almost sold it in the mid-80s to "sex guru" Bhagwan Shree Rajneesh. Rajneesh was later deported, after his followers in Oregon contaminated some salad bars with salmonella, and that deal fell through.
