The red countries are those which I have visited. The grey are those I have not. There is the issue of Austria. I once was on a mountain which formed the border between Germany and Austria but I am not sure if I actually did cross into Austria. Then of course there is the other issue of Egypt and Bahrain where I did not get off the plane. Ireland simularly I did not get out of the airport.

Since TulipGirl had a map of the States where she had been, I figured there must be a map with the countries too. So, sort of a hat-tip to TulipGirl
