During a recent trip to Scotland, I learned that rolling hills demand comfortable walking shoes, fall weather calls for layers, and a visit to the Highland cows just might require allergy medication. I've been lucky enough to travel to the UK several times, but this was my first visit to the charming city of Edinburgh . As I quickly learned, packing for Scotland is an adventure in itself. And although I got some things right, there were definitely a few items I wish I'd brought in my suitcase.
