Backbone routes cannot be concealed. How could they be? Prior to any
plow ever hitting the ground or strand strung between poles there are
(sometimes very lengthy) environmental impact assessments, permits
issued, RFPs/RFQs and awards to have the work done, USGS surveys, ROW
franchises issued, and more, that are all a matter of public record.
Not to mention the hoards of gawkers lined up along roadsides
supervising trenchers as they tear apart the countryside laying down conduit.
The routes themselves cannot be concealed, but the tenants who reside
in the conduits, and those who piggy-back atop primary providers,
often can.
