I'd agree with Findlay. I don't know if it was just some of the properties he ended up with, or not, but he seemed to relish taking the golfer on some wild up, and downhill rides! Another local one, Valley Forge, will soon be NLE. Too bad, as it's the last bit of green expanse in the concrete and asphalt jungle known as King of Prussia. What is regarded as his best course, by the way?
Cornish has an extensive array of serviceable courses, mostly public, as mentioned.
Another PA local, Jim Blaukovitch, has nicely filled a niche:
Honeybrook,Golden Oaks, Old Homestead , Bella Vista etc.
