Not Red Rock Island?<p>That's privately owned, and currently for sale. Great location, south of the Richmond Bridge. It's a 5 acre big steep-sided rock sticking out of deep water. Nobody has ever been willing to spend enough money to do anything with it. Even conservation groups don't want it.<p>The price has gone from $49,000 in 1954 to an asking price of $25 million now. No takers.<p>[1] <a href="https://en.wikipedia.org/wiki/Red_Rock_Island" rel="nofollow">https://en.wikipedia.org/wiki/Red_Rock_Island</a>
