I visited Scotland for 6 weeks and stayed with my family. My uncle suggested getting a map and highlighting everywhere we went. We actually went to every area except the border country and John O'Groats. I loved my time there and cried when it was time to leave. It's just so beautiful! Fort William, Inverness, Ayr, Edinburgh, Glasgow, but the Isle of Skye was my favorite spot.
My aunt and uncle in Scotland tried to live in the US ages ago and my parents were their sponsors, but they missed Scotland too much.
