Salt Lake to Chicago to Dulles to Brussels to Kinshasa to Brussels to Bucharest to Zurich to Ljubljana to Tirana to Vienna To Frankfurt to Chicago to Salt Lake. Probably one of the busiest trips I ever took. By 2003, my passport had 3 extensions in it and looked like a paperback book. The security people always asked me a lot of questions about why I was traveling to these bizarre places, which also included Serbia, Croatia, Bulgaria, Turkey, Egypt, Spain. France, Italy, Malta, and a bunch of others along the way.
It was a great 10 years.
