...I am now committed. I have booked flights to Edinburgh and train tickets to Inverness. I have booked a b&b in Inverness and a travelodge and b&b in Edinburgh. The Loch Ness Marathon beckons, as does a (hopefully) well-deserved sojourn in Edinburgh. In other words, the easy stuff.
As an aside, I love train travel (I've spoken about it before) and would happily catch the train up to Inverness. Except my total travel costs for flights and trains is still less than half the price of the return train journey from Bristol to said city. Which is oddly ridiculous. And somewhat saddening.
