And then there is also the choice *not* to make it a short Par 5, which, given the love many golfers have for that type of hole, is for me an admirable one. The long 4 'works', when it does, in part because of the architect's awareness that most of us - sophisticates and Joe H aside - really do want to hit a green in regulation, i.e. we really do take 'par' seriously. The trick the architect then sometimes manages to pull off is providing a genuine (if differing) challenge to all of us while at the same time not demoralizing the weaker players among us. It is so much easier, and will likely be much more popular, just to make a Par 5 out of the crappy land instead; then, when bogey golfers bogey them, as they often do, at least they only blame themselves and not the architect (the concept of 'par' seeming to still have been validated and respected). And that choice, I think, is one of the reasons, maybe the main reason, why I come across so many banal/uninteresting Par 5s, i.e. they've been created more by default (a doubt about managing to pull off a much-liked long Par 4) than by sincere intention.
