When I was learning to fly, my instructor spent a lot of time on pilotage, pointing out rivers, ridges, highways, railways, and other landmarks that could guide me to interesting destinations or, more importantly, back to the airport if all else failed.
I am glad he took the time to do that because I still find myself navigating by sight a lot of the time, finding my way by following terrain features. Among my favorites is the Susquehanna River, which meanders across Pennsylvania, passing near numerous points of interest including airports like Bloomsburg (N13), which is right on the river, and Sunbury (71N), situated on an island in the middle of it.
