Backbone links
Connects to Mount Diablo using an 3GHz airFiber.
From discussions on weekly meeting it's clear that CCCC is willing to host many more nodes as part of the backbone project.
Unfortunately the proposed link to San Pedro is blocked by a tree. A longer term solution is to use the old telephone pole (left in the picture) as a mounting point instead.
