We try to pick our courses carefully because we have limited time. Fortunately, the folks here help us choose wisely. We do not get to play private courses too often so I have no view on bashing public versus private. However, I agree with Sean that folks tend to be polite about well known courses/designers. We have played four courses in the past few years that I think are vastly overrated:
Castle Stuart
Kingsbarns
PH4
PH8
I am not in the golf business so I do not care what people think. But then again, that means that they do not care what I think.
But more thick skins would be a good thing.
