Another bottle of wine gets opened and the guidebooks come out. Our own treasure maps. Tracing lines across the highlands; there are castles, snow-capped mountains, lochs and ruins on the doorstep. Another coast to explore. It's decided.
The next morning sees an early start, fuzzy-headed but hearts clear. A whirlwind tour of the highlands - tiny daft roads barely big enough for a skateboard, camera and notebooks in tow, Rob's on the music, Sarah's got the map.
Adventure calls all the time; you just have to answer it.
