I have it. It is a chronic re-occuring disease I caught whilst on my first trip abroad. If more than a year goes by without me visiting a new place, I get antsy. My mind wanders, I begin dreaming about where I want to go and I begin talking about it with anyone willing to listen.
Planning begins. Planning is almost as fun as the traveling (at least I think so).
I currently have the travel bug but am not in the financial position to travel; plus, my priorities lie somewhere else at the moment.
It will happen. Soon enough.
