Tom MacWood et al:
It seems to me, in a general sense, the entire philosophy of bunkering on golf courses went through a number of considerations for a number of differing reasons.
First, the consideration of what more bunkers or less bunkers meant as to good or interesting golf. Of course this could've meant good and interesting golf in the context of strategies in play as well as some aesthetic context. Some seemed to be of the belief that more bunkers automatically meant better golf and better aesthetics in golf. Eventually others seems to get around to disagreeing with that, but why?
Eventually golf clubs and golfers realized that despite these kinds of philosophies there was very much another context and a most important one---eg economics! Basically bunkering is just not inexpensive to make and maintain.
Should not this last consideration be considered a most important one regarding bunkers?
Some think so and apparently some don't. It seem to me the ones who think so are the ones who are paying the bills and it also seems to me the ones who don't think so are the ones who never have to consider the cost or paying those bills.
One of the best recent examples of this kind of thing may be the considerations facing Aronimink with their bunker restoration. Their choices were to restore app. 80 Ross bunkers or to restore app. 220 original bunkers covering basically the same space but in sets of twos and threes in the same spots as Ross's "field drawing" single bunkers.
They chose the latter because of some considerations to the expense of both construction and on-going maintenance costs.
