Patagonia
Vietnam- well, I was there once for a while....
African safari
Egypt
I've always considered my ultimate road trip to me one lap around the Mediterranean from Portugal through Spain, France, Italy, the former Yugoslavia, Turkey, Greece, Iran, Syria, Israel, Egypt, Tunisia, Libya, and finishing up in Morocco. I know I've missed a couple, and not necessarily gotten them in proper order, but you get the idea. At my age, and in view of the current world political reality, I'm resigned that it isn't gonna happen, but it would be a wonderful trip! So far we've done 6 of these countries, including camping with Bedoins in the Sahara.
Sorry, guess I got a little away from the OP
