Going to Scotland

The little Mrs and me are going to Scotland next week for 14 days, it's her 60th birthday trip.
We will be all over the northern half of the country, away from the big cities.
Anyone have any advice or travel tip's? Cool places to see etc.
Thanks in advance
We just got back last night.
What a ride the roads are a rush, fast and really narrow.
Will try to post some pic's later.
Would highly recommend to anyone to go there, bring a lot of $
Thanks to all that posted
