One nice thing about taking lots of photos, is I can bring up the photo file on my computer, scroll randomly back and relive the adventures of the past. I have had a good life, been lots of places, seen lots of good things, met lots of interesting places, smelled the smells, heard the sounds, felt the sun and rain in a lot of places, tasted the cuisine of places new and old. And scrolling back through the pictures brings it back to me in a flash.
Athens was amazing. Looking back at 2,000-3,000 years of human history. Greece was intimidating, the language is impenetrable, but Athens was easy. There is a great train line from the airport into the city center. The city center is very walkable. Language was seldom an issue, most of the people speak multiple languages - at least enough to get by. Athens has been hosting foreigners since the beginning of time, they know how to do it. I'd go back in a heartbeat.
Where would you go back to in a heartbeat?
