On a similar thread, I used to live up on a mountain from when I was born until I was around 11. Not a massive mountain, and we lived halfway up, but a mountain nonetheless.
Now, when I was about 7-8 I'd go down to the park in the town below, maybe a mile from the house (mostly downhill). Funny thing was, this park was kind of in a "dip". If my mum ever wanted to call us to come home (this was when I had no phone - mobiles were not for children) she would stand on the garden wall, and make this COOP-COOP-COOOOOO sound.
You could hear it echoing from up the the mountain and when we all turned to look, see this manic, short, curly haired woman "coop-ing" and waving her arms. It was dinner time.
Ah, to be young again.
