Just when it seemed I'd travelled far enough north, I hoped on yet another train and found myself in the Scottish highlands. But this time I also found an old friend along the way, another person I haven't seen for five years. He lives up this way and hopped on the train to come and have an adventure. Tomorrow we're off on the Jacobite steam train, through the west from Fort William to Mallaig. I'm quite excited and desperately hoping the weather clears - it's grey and drizzly this evening.
