This Washington Post article talks about the desirability of walking and biking trails in communities. The trails can reduce traffic on roads, improve livability, and attract Millenials. But over and over I again, we see communities making multi-million dollar investments in these trails without thinking about putting in conduit and fiber.
These trails can be extremely valuable as a digital highway. You typically won't connect many homes or businesses on these routes, but these paths often provide low construction cost routes between different parts of a community or even better, low cost routes between two communities.
