Hint: most rural, semi-rural areas, many forests have one or more highways near them. The sound of the trucks can be heard for miles.

Florida scrub-pine woods can be dense and the terrain is dead flat. If the sky is overcast it is easy to get turned around if you don't have some reference. But if you wait and listen you can hear the roar of the highway pretty much 24/7.

Similarly it is rare to find a place that doesn't have regular airliner traffic over it. Airliners tend to fly set air corridors. If you know the air corridor and generally where it is in relation to you you have a good clue to your location and which way is north. Over a National Forest I frequent the air corridor is almost due East-West and just north of the forest boundary. If I hear the rumble of an airliner I can tell which way is north and if I can tell roughly how far away it is, how far south of the forest boundary I am.

This same area has a major highway on the East side. Once you know what to look and listen for it becomes pretty hard to get seriously lost.

If you frequent, or fly over, a wilderness area it can be worth the trouble to find out what air corridors are near and the regular flight schedules. Sad that it is virtually impossible to escape the sounds of modern life, I go to get away, but if it's out there it would be a mistake to not take advantage of it in a survival situation.
