Nicole, I can understand your infatuation with Scotland, it is very similar to authors I've heard talk about why they write about Ireland.
I'm happy about writing about the great USA. I grew up reading Louis L'Amour and Danielle Steel and I hope to somehow combine the two into a love story on a setting of a cattle ranch. Eventually I want to write more about the 'old west'. My minor in history is calling me to write a story set in the Civil War or American Rev era -- so we'll see.
I live very near Saratoga NY so the American Rev was right in my back yard. In college I traveled to Manassas and it called me like Scotland calls you -- so I can see myself traveling along the Civil War route for a story..
I also hope you enjoy your trip to Scotland - you need to show us lots of pictures..
