In 1980, I was living in Amsterdam and some friends and I had a much anticipated trip planned to go to Yugoslavia. Just days before we were to leave, Tito died. That cancelled trip has been my biggest travel regret, though it couldn't be helped. In reality, we all just had Eurail Passes and not much money, so who knows what it would have been like.
