I would give the Castle Course a 5, so I don't have it better. As I remember a Doak zero is a ranking usually higher than a 1, merely reserved for a course that spent too much and messed it up.
The lone tree is a hawthorn that was there from the start, so we worked around it and kept it. It's 320 off the tee uphill so does not trouble the tee shot. Everything you see bar the trees is man made as it was a totally flat almost featureless field.
The English Language is obviously very different regional, something that is nice down our way means good. It would not have any relevance to not having an opinion. Poor would be classified as shite, minging, crap. Middle of the road would be more its okay. If someone wanted to expand their reasoning why it is one of those they would.
In our area most people would have Painswick as shite, minging or crap. It's all about opinion I first played it in a junior open 41 years ago and loved it first time but I can see how many form the opinions they do.
