Hello,
Thank you for these comments, they balm most of my worries that the sense was getting away from me.
Certainly, I have a bias now reading your responses (and thank you Jim K for directing me to a germane archived thread) but sense was/is that it was mainly in "character of property" eg...if you have a piece of property that's largely rolling farmland, whereof the best routing takes a hole/holes to a culd de sac'ed section or place NOT like that, that a transition hole can be conceived to make that necessary return...or if not all one way or the other...to the next section of the property, which might be streams and meadows or a shady glen...
Again, thank you for your offerings
cheers
