Perfect length update

Interesting response to my question to Golf Monthly Forum on how many holes would be perfect for golf if eighteen weren't the norm. Although there were a few eighteen-or-bust die-hards, the majority were happy to curtail the round in favour of getting home earlier. More than one made the additional observation that some modern courses cram in more holes than they have space for. The result is holes that are not just less than satisfying, but often less than safe, with tees much too close for comfort, sometimes inviting nasty accidents.
There seems to be a lesson here somewhere. Golf is golf. Let's go for a fair challenge over the space available.
After all, that's how the game began.
