Of course knowing where the fiber is does not stop the backhoes.  It  
was obvious you were being silly, so I ignored it.  By that logic,  
providers should not check any fiber path they purchase because it  
will not stop the backhoes.  I suspect most providers will continue to  
buy from multiple providers, check the paths themselves, ensure  
grooming onto a single path is not a problem, and several other  
perfectly valid operational best practices which are impossible at  

OTOH: My paragraph above yours is a serious consideration, which you  
have blithely ignored.

As I said before, feel free to use what you please, where you please.   
Your network, your decision.  I frequently do things which would not  
be considered best practices in certain instances, but that does not  
make them valid for everyone everywhere, and I would not argue such.
