Where is a place you would not or should not find gravel?

The Sun

In my pockets.

In my throat (despite what it may sound like).

In my lunch.

Inside of an engine

In your mouth, ears, or any other body hole.

Armpits.

In a bra. This post was edited by Kittigate at March 28, 2022 8:00 AM MDT

In the living-room carpet.

Why that?

The question reminded me of my girlfriend and I once taking a walk around the much-vaunted "Poundbury" near Dorchester (S. England). This pseudo-village is a huge housing estate sprinkled with various business premises, built in what I call "Nouveau Pastiche" style - which at least is an effort to break away from lots and lots and lots of identical houses.

Living about twelve miles away from it, we visited it when its first phase had just been built, out of curiosity; and decided we'd not live there even if we could afford its Nouveau Pastiche prices.
 
Its small terraced houses have tiny back gardens, no obvious car-parks near them, and front doors that open straight onto narrow pavements.

The pavements were dressed in fine gravel... Just right for being carried on your shoes into your home!
