Friendly speaking, I think that the idea to revive tradition to write letters from abroad is not a bad one. You know, kind of 19th century fashion "My dear N. I'm longing to tell you a fascinating story about our recent visit to M".
New cities will be playing the role of balls (though somebody may be a lucky one and buy a ticket to the ball in opera theatre of Vienna )))) and new people and delicious food will remain at their places.
And , yeah, I was in the Dresden Gallerie and I saw Sistine Madonna and pictures by other Old Masters. And it's real shame that it was me, not the persone who really likes art.

But long boring story about it later, if I have time, inspiration and live Internet ))
