Mark:
I've played a great number of Ross courses and would say that not all of the are greatly memorable, yet with a few exceptions they were enjoyable.
I cannot understand why anyone would want to build a golf course that would feature memorable hazards unless they were trying to sell adjoining real estate to the people that play golf (as opposed to golfers).
There are a number of Ross courses that are truly memorable. I would put Salem, Brae Burn, Essex County, the Orchards, Wannamoisett, Newport,Wykagil, Oak Hill, Teugega, Aronimink, Plainfield, Pine Needles, Mid Pines, #2, Mimosa Hills, Highlands, East Lake, Athens CC and Seminole on that list. There are many others in the Midwest that would make the list.
These courses are memorable as 18 hole entities, not dependent on a certain freakazoid hazard that stands out like the naked chick at Mardi Gras.
Did you ever think that Mr. Ross designed his greens to be the ultimate hazards?
