Spain is a perennial favorite with Andrew Harper members, and with good reason. I always feel excited to have an excuse to return. Most travelers focus on Madrid, Barcelona and Andalusia in the south. But this time I turned north to Galicia, a Celtic region that in some ways has more in common with Brittany or Ireland than it does with the rest of the country. I’ve lost count of my visits to Spain, but this trip still felt like a journey into the unknown.
