I didn't know about the in-transit permits until a month before I left. I put a great deal of blame on the travel agent who was supposed to specialize in trips to Africa, but first he didn't know anything about the permits, and secondly he booked us on Northwest; Winnipeg, to Minneapolis, to Detroit, to Amsterdam to Dar. Getting the permit for the Netherlands wasn't a problem, getting a rifle into Tanzania wasn't a problem, getting the permit from the US was going to take 6 to 8 weeks. The rifle I had invested 4 years and a pile of money on stayed home. It all worked out, but bitterly disappointed doesn't even begin to describe how I felt when I realized the rifle would stay home rather than risk losing it.
