We're looking to rent (hire) a car outside of the city of Edinburgh for the day. Being from the States (as well as our 1st time driving on the other side of the road....to us!), we wanted to start outside of the city. Our goal is to aimlessly drive the Highlands, enjoying the scenery, small towns, etc. We plan on getting an early start and returning in the evening. We would like to take the bus (even the train if necessary) to get to a good starting point. Any suggestions?
