We're beginning to plan a trip to Scotland in May, 2017, a special time for us. Can we just fly in and rent a car as we might here, or must we get a special license before driving there? Alternatively, how extensive is the public transportation system? I suppose we'll fly into Edinburgh and travel generally northward toward Inverness, with a mandatory stop in Culross, The Woman's ancestoral home. Nothing specific planned, and no idea how long we'll stay as of yet.
