You guys are kidding, right?
Anyone who has ever seen San Quentin - and it's tough to miss from many nearby roads and highways - can tell you that it's a small city filled with massive buildings and infrastructure. The cost to tear all of that down and transform the land into a golf course would have to be STAGGERING.
That being said, if some gazillionaire individual or company with zero financial concerns wanted to do this - and could get by what would have to be the massive regulatory and environment issues also - well then yes, it is some fine bay-side land with very nice views. As with all landforms anywhere near the Bay, yes it is quite windy there.
