In thinking back on the last five courses I provided names for, they were all concocted while sitting on airplanes, very likely with a gin and tonic in hand.
I think there is more to be gained by naming than not. While some here are "bashful" or "worried" about what others might think too pretentious, too hokey, etc. I think the nature of assigning a name to a golf hole (or feature in some cases) brings the experience to life. A majority of people will find names amusing, interesting and it will also help them remember their experience.
One of the more interesting comments on televised golf is the background of a golf hole the name of a tree, hole or story that goes along with the design and strategy. I think it a lost opportunity if we take the presumption that names will be taken as hokey or contrived. In actuality, people enjoy something other than numerals to define their way or space.
My work with Disney confirms perception in this area: Just the simply act of naming the cars in Mr. Toad's Wild Ride is, in itself, a simply, yet thoughtful act that has amused generations of customers of the Disney Parks.
Anyone here who thinks golf is not entertainment must be having a bad hair day.
