@littlek,
I was stationed in Scotland in the mid 80's. Absolutely beautiful countryside with a castle on every loch. Should you go,
Stirling Castle is a must see. This is not some show castle build to house government, this is the real thing with fireplaces big enough to cook a full spitted cow and stone battlements where the stairs have been noticably worn down by 500 years of rain. Extremely impressive! I also recommend
Oban, a quaint port city with spectacular views and lots of shops and restaurants, the self proclaimed "seafood capital of Scotland".
