Look guys, there isnt a completely natural golf course anywhere in America. I dare anybody (especially the naysayers on here) to show me a course where they moved no dirt, imported no sand, all natural green sites, no irrigation, no chemicals and no capital investments made to it, oh, and it gets maintained by the sheep. Im sure if we look into each of the naysayers home courses or courses they build or maintain, we would find very "unnatural" golf courses. And whats with the "Anti-Drip Irrigation" faction on here? Use your heads guys!!!! If it wasnt drip irrigation on those faces it would be Toro or Rainbird golf sprinklers throwing water inaffectively and inefficiently. Drip irrigation is nothing but a tube emmitting water EXACTLY where it needs to go, 100% efficiency. Drip irrigation isnt some over the top ultra expensive maintenance option. And like the one guy said, they are to APPEAR natural. How many bunkers in America are natural? So whats wrong with Merion spending their OWN money to have great bunkers?
