How do those untrenchable locations receive water and sewer? If water and sewer can be installed underground, why not fiber? Isn't it just that traditional trenching would have been too expensive for Google to justify? Google apparentl

You don't need realpath. The `cd` into the directory + `pwd` is equivalent. BASH_SOURCE[0] obviously only works with bash.
