It was a green, green time in Slovenia last month.

Especially so for those of us participating in a tourism-themed “Global Green Destinations” conference. We learned about “Green Solutions” and the “Slovenia Green” program and “Green Experiences,” and we did it all in Europe’s official Green City for 2016: Ljubljana, the country’s capital. Even the castle-fort that overlooks the historic old town was awash in celebratory green nighttime lighting.
