The slight creuse (hollow - ha ha) in my drive is a legacy from the numpty who thought the fosse septique was there when we couldn't find it and we needed it drained to link up the foul waste pipe to the 'tout a le gout' (?) in the street (who says my french never improves?). He had dug a hole with his digger while we were out and was standing over it looking puzzled and yes, slightly embarassed when we returned. He had decided that was the location after dowsing for it! C'est la vie for sure en Creuse.
