I just got back from my buffalo hunt w/ Vaughan Fulton, great trip, photos later. Just wanted to give some guys going across some current info.
There is a new customs form 4457. Lufthansa made me go to customs in LAX & they gave me a new form. Same form, but now has the ICE stamp.
I flew through Frankfurt, baggage forwarded through AirNamibia no problems. On the way home, we wanted to spend some time in Germany. Leaving the rifle & ammo w/ Customs was quite easy & took maybe 30min each way, no hassles & no charge. If you want to go this route, it's worth it IMO, you are already over there & it's a nice change after 7-10days of hot hunting weather.
