I'm healthy, mid-50's; she's healthy, mid-70's, both travelers, love to walk, drive, stay in new places on a budget, and are low-maintenance (but do want clean and safe lodging). Will be exploring Mom's roots: her father was from Denmark, mother from Norway. We think Copenhagen and Trondheim, but they seem very far from each other. Oslo would be good to see, too- distant relations there are possible (we're searching records now). Don't know where to start to plan an excellent, 10-day road/rail trip in June or July, 2013. All help and suggestions gratefully welcomed! (We're skillful planners: just need suggestions for reliable resources, as this part of the world is new to us).
