[Greenbuilding] Doorbell options

[Kathy Cochran]

My experience with Black (or Chocolate) Labs is that they soon learn that
"every human being" is "wonderful" so they bark with the same enthusiasm no
matter who it is.  Yes, they eat a lot, and require maintenance, but they
give you unconditional love no matter who you are or what you do, so that
cannot be removed from the equation of what is "worth it."  

Cheers,

I would guess that a dog would be one of the most inefficient doorbells one
could find.  They may not use electricity, but they use a lot of food and
require constant maintenance.
