Privatopia

This isn't just funny but it is, also, too, funny.

Tina Lam and Michael Cheng snatched up Presidio Terrace — the block-long, private oval street lined by 35 megamillion-dollar mansions — for $90,000 and change in a city-run auction stemming from an unpaid tax bill. They outlasted several other bidders.

Now they’re looking to cash in — maybe by charging the residents of those mansions to park on their own private street.

Those residents value their privacy — and their exclusivity. Past homeowners have included Sen. Dianne Feinstein and her financier husband, Richard Blum; House Democratic leader Nancy Pelosi; and the late Mayor Joseph Alioto. A guard is stationed round the clock at the stone-gate entrance to the street to keep the curious away.
