Coldstream is a good, solid golf course. It was built on the family farm of the Williams family, who used to own the Cincinnati Reds back in the day. Like many courses, it used to be fairly treeless, but now has thousands of trees, which come into play on, with a few exceptions, every hole.
It is similar to other Dick Wilson courses, like NCR South. I do think NCR is the better course...better property, better par 4s. Coldstream is a tough course, though, and they have many good players as members whose handicaps travel very well.
I think the best hole is #14, a par 3. Like most holes there, the green is HUGE, sloping from front to back a bit but right to left a lot. Depending on the hole location, it can be anything from a wedge to a 7-iron. The green makes the hole.
The 18th green is like 70 yards long. When I played there a few months ago, my host told a story of some guys who were enjoying some adult beverages on the patio overlooking the green. One guy announced that he could punt a football from the back of the green to the front on a fly. Another guy quickly said "I'll bet you $100!" He then went to his car's trunk, got a football, and watched as the first guy didn't get it half way to the front of the green.
