Fixed-wing, but ....
I was looking for a bush strip on a very hazy day in the middle of nowhere, Nigeria, pre-GPS, when I finally had to give up and go to Makurdi, the nearest place I knew how to find, hard to miss because it's sited right on the Benue River.
When I got there I found a Nigeria Air Force fighter pilot wearing a spiffy grey leather flight jacket, even though it was 30º in the shade. He told me to follow the road south and to look for a hill that "sticks out like a dog's balls" and then to hang a right to follow the road that led to the Benue Cement airstrip at Gboko.
By God that hill did stick out "like a dog's balls," too!
