re Pasatiempo, Steve is right on - not even close to the infrastructure required, unless they start tearing down houses.
But on top of that... it's way way way too short. Oh they could keep scores reasonable if they made it massively fast, crazy high rough, silly hard pins... but how stupid would that be?
On top of that.. hard to call it really "public"... semi-private is more correct.
I love Pasatiempo. But a US Open site, particularly one repesenting public courses? No way.
