My questions are:
Should we set up "base camp" in Glasgow or in Edinburgh? or some place in between? We can fly home from either (slightly cheaper from Glasgow).
We would like to visit some countryside sites, so a car will be worthwhile -- however, I understand that having a car in either Glasgow or in Edinburgh is "challenging". Any advice?
We are outdoor, castle-curious, not-too-big-on-museums types (and based on having double posted my message on the Glasgow forum, not too computer talented!).
