If Dimitris happens to be passing by your city or somewhere around where you are and you would like to meet him, feel free to e-mail him.
He will contact you, when the time is right, either to meet you over a cup of coffee or just to thank you. Maybe it will be a good chance for you to show him around.
This trip, one way or another, depends greatly on your support. Look at the basic destinations of the journey and put forward your own suggestions about the people I should meet, the places I should visit or even avoid for some reason.
