I'm thinking a few courses are probably better thanks to water restrictions. There may be others that have been inadvertently improved by a street that got routed right through their worst hole, forcing them to build a better one elsewhere. Still others may have been improved by something as simple as a local noise ordinance.
And seriously, how does one look at photos of Fossil Trace and not think "Hmm, maybe Engh had a feeling Amendment 64 was coming"? That chimney in the middle of the first fairway looks pretty far out, man.
