Has anyone taken their rifles to Customs and Border Patrol in Nashville recently? I went there last week and was unable to get in touch with anyone. The office is no longer outside of the airport, but is in a restricted area without general access. I called with no success. Looking for feedback on how to get this taken care of. Last time I flew internationally with firearms, I was in the Indianapolis area. The office was outside the airport and it was a quick and easy process. Help!
